(concurring in part ancl dissenting in part). The defendant was convicted of armed robbery.1 At the trial a loaded handgun, found *102during a search of the defendant when he was arrested two days after the crime was committed, was introduced in evidence over his attorney’s objection. The victim identified the defendant as the robber but could not identify the gun.2

There was no evidence that the gun found on the defendant was used to commit the crime. Nevertheless, I agree with my colleagues that it is well established that where weapons or tools are used to commit a crime, weapons or tools which might have been used to commit it, found in the accused’s possession, may be introduced without proof that they were the very weapons or tools which, in fact, were used in its commission.3 It is also well established,4 *103however, that the trial court may, in the exercise of its discretion, and, in some cases is obliged, to exclude evidence otherwise admissible because its probative value is overcome by the danger that introduction of the evidence will confuse, mislead or prejudice the jury.* ****5

The fact that the defendant Hall owned a gun was relevant. It is ordinarily a reasonable inference, one which the trier of fact may properly draw, that one who owns a gun on a given date owned it two days before that date. If the jury drew that inference it could properly conclude that Hall had the capacity to commit the crime of which he was convicted.

*104The defendant’s objection to the admission of the gun was not put on the ground that it was not relevant. The defendant asserted, rather, that its introduction was prejudicial and, therefore, even though relevant, the gun should not have been admitted into evidence.

The crux of the people’s case was the identification testimony of the taxicab driver who was the victim of the armed robbery. The introduction of the gun did not serve in any way to aid the jury in properly evaluating the taxicab driver’s identification testimony.

Possession of a handgun is regarded by a significant portion of our citizens as reprehensible. Thus, there was considerable risk that the jury would give undue weight to the fact that the defendant Hall owned a gun and on that basis resolve against him any doubt regarding the identification testimony. Confronted with such a situation, our duty and that of the trial judge is to balance the relevance of the evidence (its probative value) against its diversionary and prejudicial impact.

Analogous on its facts is State v. Thompson (1961), 228 Or 496 (364 P2d 783). The defendant in that case was arrested two months after the commission of the armed robbery at his home which was situated 75 miles from the scene of the crime. The gun was found on a shelf in a closet in the defendant’s bedroom. The defendant was identified by the victim as the robber. The analysis of the Oregon Supreme Court in holding that the trial judge in that case should not have allowed the gun to have been introduced in evidence is persuasive (pp 501, 502) :

“Admittedly, cases involving weapons found on or about a defendant when arrested and which cannot be identified as the actual weapon with which *105the crime charged had been committed present difficult questions of admissibility. In the absence of any direct or indirect evidence of identity or similarity it may become a problem of the time and place where the accused is apprehended and weapons found in respect to the time and place of the crime committed, or, it may be that evidence of some unique character of the weapon which might have been used to commit the crime in respect to the weapon found upon one accused of the crime would render it admissible. Thus a gun taken from the hand of a person found standing over a murdered victim would be admissible even though no other identification was available. Or in the more usual situation when an accused has been observed secreting a weapon or attempting to throw away a weapon in flight the connection between the weapon and the crime is definite.

“At the other extreme is a case like the one now under consideration. The accused was arrested in a normal home atmosphere. The crime was committed two months before at a place about 75 miles distant. The gun found and admitted was not unique or distinguishable from the other .22-caliber revolvers that could probably have been found in many homes within Klamath Falls, or any other city, at the time of defendant’s arrest. There was no testimony that the gun was similar to the gun that had been seen by the robbery victim. There was nothing to tie this revolver to the crime alleged other than it was found in the home of the man charged with committing the crime.

“In most instances the admissibility of evidence of this character must be left to the discretion of the trial court. It would be impossible to narrowly delineate the exact limits of admissibility within the varying degrees of connection that could exist. Imagination can devise innumerable hypothetical cases which defy solution by any hard rule. The question must be resolved within the facts of each case. In this particular case, however, we think the *106prejudicial character of the evidence outweighed its probative value.”

The reasoning of the Oregon Supreme Court is apposite even though the defendant in the cited case was arrested two months after the crime was committed while in this case the defendant Hall was arrested two days after commission of the crime. In both this case and the cited case the accused was apprehended at a time which was not contemporaneous with the commission of the crime6 and the connection to the crime of the gun found in the accused’s possession was largely conjectural.7

The Iowa Supreme Court has also had occasion to balance the value of relevant evidence as a contribution to the solution of the fact issue against the danger of its diversionary or prejudicial effect upon the trier of fact. State v. Slauson (1958), 249 Iowa 755 (88 NW2d 806); State v. Wallace (1966), 259 Iowa 765 (145 NW2d 615). Cf. State v. Kehr (1907), 133 Iowa 35 (110 NW 149). In the Wallace Case the court observed (p 771):

“Evidence which has no tendency or only a slight tendency to establish guilt or innocence of an ac*107cused, or which if effective at all could serve only to prejudice, mislead or excite the passions of a jury, should not be admitted.”

Recently in People v. Turner (1969), 17 Mich App 123, our Court held that a trial judge abused his discretion in allowing the introduction in a murder case of a particularly gruesome autopsy photograph of the victim. In so holding we balanced the admitted relevancy of the evidence against its prejudicial impact and concluded that the “photograph of the skull was not of such essential evidentiary value that its need clearly outweighed the likelihood that it would inñame the minds and passions of the jurors.” Cf. People v. Auerbach (1913), 176 Mich 23, 39, 41; People v. Besonen (1966), 4 Mich App 131, 139; People v. Nichols (1954), 341 Mich 311, 330-332; People v. Brocato (1969), 17 Mich App 277, 302; People v. Eldridge (1969), 17 Mich App 306, 313; Taylor v. Walter (1968), 15 Mich App 361, 364.

Professor McCormick, in his treatise of the Law of Evidence, succinctly stated the issue (§ 152, p 319):

“Relevance is not always enough. There may remain the question, is its value worth what it costs?”8

*108' Where the people’s case is based largely or entirely on circumstantial evidence,9 unlike the people’s case here, the probative value of the evidence will generally outweigh the danger of confusing the issues or prejudicing or misleading the jury. For, in such a case, the jury needs to know that the defendant had the capacity to commit the crime. In the three Michigan cases of which I am aware, where evidence of weapons or tools found in the accused person’s possession was held admissible to show capacity to commit the crime, the case against the accused was largely or entirely circumstantial. People v. Courtney (1913), 178 Mich 137, 153; People v. Lahnala (1916), 193 Mich 144; and People v. Winney (1917), 196 Mich 347, 365.10

Carrying a concealed weapon is a crime.11 Although the jurors were not told in so many words that the defendant had committed that crime, most citizens know and, indeed, are required by the law to know, that carrying a concealed weapon is a *109crime. In a very real sense then, what the people were allowed to prove in this case was that the defendant’s conduct on another occasion was the conduct of a had man.

The law generally12 excludes evidence of similar occurrences and transactions in both civil and criminal cases, not because the evidence would be irrelevant, but because of the danger that the trier of fact will conclude that “with all that smoke there must be a fire.”

This general policy is unnecessarily eroded by allowing the kind of evidence that was used in this case. Experience tells us that when in doubt, and there may very well have been reasonable doubt of the defendant’s guilt in this case considering the conflict in the testimony and the circumstances, the jury may resolve that doubt on the basis of the extraneous evidence put before it that the defendant was a bad man.

The people did not seek to build their case against Hall upon circumstantial evidence (e.g., possession of weapons or other tools with which to commit the crime, and of identifying clothing13 and of the stolen goods, etc.). The relevance of the fact that the defendant Hall owned a gun was a theoretical relevance unrelated to the people’s theory in this case. The fact that the defendant owned a gun was not tied in to any other proofs. The people could not have prevailed by proving only that the defendant *110owned a gun and thus had the capacity to commit the crime.14

The defendant’s ownership of a gun had no logical or rational connection to any other evidence in the case. That fact was not part of a composite of proofs from which the defendant’s guilt could have been deduced. The fact that the defendant owned a gun was left suspended before the jury, completely unrelated to any other evidence in the case. It served but one purpose, to confuse and mislead the jury, to divert it from the central issue of identity, to prejudice the jury against the defendant, to resolve any doubts that the jury entertained regarding the identification testimony on the basis of the fact, legally irrelevant, that the defendant was a bad man.15

Having in mind the people’s theory, the minimal relevance of the gun, the diversion from the predominant issue — identification—and the prejudice to the defendant accomplished by introduction of the gun, I am convinced that on the facts of this case the gun should not have been introduced.

I agree with my colleagues’ disposition of the sentence credit issue as set forth in Judge Holbrook’s opinion.

*111 APPENDIX

The problem of balancing the probative value of evidence with the danger of undue prejudice, confusion of issues, or misleading the jury is presented whenever a witness (and particularly when a defendant) with a criminal record takes the stand and it is sought to question him regarding his criminal record ostensibly for the purpose of enabling the jury to judge his credibility as a witness.

It is safe to say that the use of past criminal record to attack credibility has become so customary that it is rarely challenged. Recently, however, our Court in affirming a jury verdict of no cause of action in a personal injury case held that the trial judge did not abuse his discretion in refusing to allow cross-examination of the defendant concerning prior traffic violation convictions. Taylor v. Walter (1968), 15 Mich App 361, leave to appeal granted 382 Mich 773. We relied on Zimmerman v. Goldberg (1936), 277 Mich 134, and also observed (p 364):

“Michigan follows the rule suggested in Rule 303, Model Code of Evidence which permits a trial judge in his discretion to exclude admissible evidence if he finds that its probative value is outweighed by the risk that its admission will create substantial danger of undue prejudice. See McCormick, Evidence, § 42, pp 87-94, and § 152, pp 319-321.”

The relevant statute provides:

“No person shall be excluded from giving evidence on any matter, civil or criminal, by reason of crime * * * ; but such * * * conviction of crime may be shown for the purpose of drawing in question the credibility of such witness, except as is hereinafter provided.” MCLA § 600.2158 (Stat Ann 1962 Rev § 27A. 2158).

*112In Luck v. United States (1965), 121 App DC 151 (348 F2d 763), the United States Court of Appeals for the District of Columbia, in a two-to-one decision, held, under a statute reading fundamentally as does Michigan’s, that a trial judge may, in the exercise of discretion, exclude evidence of prior crimes. In so holding the court emphasized that the statute (p 156, 348 F2d 768):

“says, in effect that the conviction ‘may,’ as opposed to ‘shall,’ be admitted; and we think the choice of words in this instance is significant. The trial court is not required to allow impeachment by prior conviction every time a defendant takes the stand in his own defense. The statute, in our view, leaves room for the operation of a sound judicial discretion to play upon the circumstances as they unfold in a particular ease. There may well be cases where the trial judge might think that the cause of truth would he helped more by letting the jury hear the defendant’s story than by the defendant’s foregoing that opportunity because of the fear of prejudice founded upon a prior conviction. There may well be other cases where the trial judge believes the prejudicial effect of impeachment far outweighs the probative relevance of the prior conviction to the issue of credibility. This last is, of course, a standard which trial judges apply every day in other contexts; and we think it has both utility and applicability in this field.” (Emphasis by the Court.)16

*113In State v. Hawthorne (1967), 49 NJ 130 (228 A2d 682), the Supreme Court of New Jersey construed its statute, similar to both our statute and the statute construed in Luck, and, after careful consideration of the Luck decision, refused to adopt it! The Court concluded that in using the word “may” the New Jersey legislature intended to authorize any litigant at his option to introduce evidence of any witness’ past conviction record and, thus, a trial court enjoys no discretion to exclude such evidence.

Both the Luck and the Hawthorne Courts regarded their task to be the determination of the correct construction of a statute and did not regard themselves as possessing any power independently of the statute to declare whether such evidence is admissible. In contrast, the Michigan Supreme Court in Perin v. Peuler (On Rehearing, 1964), 373 Mich 531, held that it had the power to declare without further force a statute making inadmissible evidence of a conviction of a motor vehicle violation; the Court stated (p 541) :

“The function of enacting and amending judicial rules of practice and procedure has been committed exclusively to this Court (Const 1908, art 7, §5; Const 1963, art 6, § 5); a function with which the legislature may not meddle or interfere save as the Court may acquiesce and adopt for retention at judicial will.”

Recently, in People v. Eldridge (1969), 17 Mich App 306, our Court, citing Luck, reversed a defendant’s conviction of statutory rape for, among other reasons, the prosecutor’s questioning of an alleged res gestae witness regarding his conviction of taking indecent liberties with the girl who complained against the defendant Eldridge.

In Eldridge we referred to Burg v. United States (CA 9, 1969), 406 F2d 235, where the defendant’s *114earlier conviction for theft was held admissible in his trial for bank robbery. One judge adhered to the orthodox rule that such evidence is always admissible for the purpose of impeaching a witness’ Credibility even though he is the defendant. Another judge adopted the approach of the Luck, Court but held that the trial judge correctly exercised his discretion. The third judge found it unnecessary to express an opinion. See, also, United States v. Palumbo (CA 2, 1968), 401 F2d 270; United States v. Hildreth (CA 4, 1967), 387 F2d 328 (dictum); State v. Dunn, (1967), 91 Idaho 870, 879 (434 P2d 88, 97) (Spear, J., concurring).

Commentators generally are critical of rules allowing evidence of prior conviction record to be admitted to impeach a defendant when he takes the stand as a witness. Professor McCormick in his work on Evidence, § 43, points out that the present rule is an historical accident. See, also, Note, Other Crimes Evidence at Trial: of Balancing and Other Matters, 70 Yale L J 763, pp 774-778 (1961); Note, Constitutional Problems Inherent in the Admissibility of Prior Record Conviction Evidence for the Purpose of Impeaching the Credibility of the Defendant Witness, 37 Cinci L Rev 168 (1968).

Both the Uniform Rules of Evidence Act (Rule 21; 9A ULA p 607) and the Model Code of Evidence (Rule 106), would eliminate the use of such evidence against a defendant in a criminal case unless he first introduces evidence admissible solely for the purpose of supporting his credibility and then would limit such evidence to convictions of a crime involving “dishonesty or false statement.”

It has been suggested that the present rule unconstitutionally chills a defendant’s right to take the stand in his own defense17 and that it “effects an *115anomalous disinction between defendants with and those without a criminal record in the exercise of the right to testify in their own behalf.”18

The defendant was convicted of robbery armed.* 1 At the trial there was introduced in evidence over defendant’s objection a loaded hand *98gun found on defendant when he was arrested two days after the crime was allegedly committed. The victim was asked whether he had a good look at the gun, to which he replied that “I didn’t look too straight at it.” When asked the color, he testified, “It was blue steel, I think it was. I don’t know for sure.”2 He later testified that it was black. The victim was then asked whether it was a revolver, to which he replied that, “I couldn’t tell you for sure. All I knew was that it was a gun.”

The victim testified that the gun used by the defendant in holding him up was fired into the ground as a warning. An officer of the police scientific laboratory, who examined the gun found on the defendant a few days after the defendant’s arrest, testified that he did not examine it to determine whether it had been fired.

Although the evidence did not establish that the gun found on the defendant at the time of his arrest was the gun used in committing the crime, it is a well-established rule that where weapons or tools were used to commit a crime, weapons or tools that might have been used to commit the crime found in the accused’s possession at the time of arrest may be introduced without proof that they were the very weapons or tools in fact so used.3

The information charged that the crime was committed “with a dangerous weapon, to-wit: a .25 cal. Astra blue steel automatic-pistol, serial #753425.” (Emphasis supplied.) The serial number so stated was the serial number of the gun found on the defendant at the time of his arrest. The people were *99unable to prove that the gun found on the defendant was in fact the gun used in committing the crime. However, in our opinion, all the emphasized quoted words other than the word “pistol” are surplusage and may be ignored.4

There was sufficient evidence to justify a jury verdict that the defendant was guilty of the crime charged beyond a reasonable doubt.

The trial court erred in failing to give the defendant specific credit against the sentence of 3 to 15 years in prison for the time he served in jail between the time of his arrest and the time of sentencing, as provided for in the applicable statute:

“Whenever any person is hereafter convicted of any crime within this state and has served any time in jail prior to sentencing because of being denied or unable to furnish bond for the offense of which he is convicted, the trial court in imposing sentence shall specifically grant credit against the sentence for such time served in jail prior to sentencing.” MCLA § 769.11b (Stat Ann 1969 Cum Supp § 28.1083 [2]).

At the time of defendant’s arrest he had escaped from the Detroit House of Correction where he was serving a state prison sentence. At the time of his arrest and at subsequent appearances before the court, bail was set at $5,000 with two sureties. Defendant did not furnish bail and he was detained in the Wayne county jail from the time of his arraignment on the warrant on September 10, 1966, through the date of trial, March 20, 1967, and the sentencing on April 5, 1967. The total period of his detention for which he claims credit is 207 days.

After oral argument in our Court the people furnished us with affidavits stating that the depart*100ment of corrections has given the defendant credit for the 207 days served in the Wayne county jail against sentences still not fully served imposed upon the defendant following earlier convictions for other offenses.5

In People v. Chattaway (1969), 18 Mich App 538, our Court observed that in Michigan, with exceptions not here relevant, a sentence may not be imposed to commence upon completion or expiration of another sentence (In re Carey [1964], 372 Mich 378, 380). It was said that the sentence credit statute avoids unnecessary chilling of exercise of the right to trial by requiring adjustment of the sentence of one denied or unable to furnish bond so that he spends no longer in jail than one receiving the same sentence who is released on hail pending trial.

This statute is remedial and has been liberally construed by our Court so as to effectuate its purpose. People v. Havey (1968), 11 Mich App 69; Booker v. Judge of Recorder’s Court (1967), 7 Mich App 705, 707; People v. Grandahl (1969), 16 Mich App 221, 224, 225. In Chattaway our Court stated:

*101“Nor is there anything in the statute which makes relevant the fact that the consequence of granting-credit in this case would be to give the plaintiff the benefit of the credit against the sentences imposed in both cases. In this connection we note that the ■ sentence credit which the plaintiff obtained in the other case was of illusory benefit to him; since both sentences run concurrently, the shorter sentence in the other case was in practical effect absorbed by the longer sentence imposed in this case. If the plaintiff can only have credit against one sentence (as the people contend), surely he should receive the credit against the longer sentence imposed in this case, where it would be of value to him, rather than against the shorter sentence imposed in the other case where the credit was of no value to him.”

We adopt this reasoning. The fact that Hall received credit against his old sentences does not negate his right to credit against the present armed robbery sentence. Since the armed robbery sentence is for a longer term than the unserved portions of the old sentences, to allow the credit against the old sentences and not the new would, in the light of the concurrency of Michigan sentences, be to confer an illusory benefit. Hall is entitled to credit against the armed robbery sentence for the 207 days.

We see no need for remanding- for resentence. Pursuant to the provisions of GCK 1963, 820.1(7) it is ordered that the defendant’s sentence be amended specifically to grant him credit for the 207 day period.
