In re: Floyd Grigsby, applying for writs of habeas corpus and remedial writs.

Writ denied; We find no merit in the reasons urged by the petitioner for the unconstitutionality of La.R.S. 15:571.7 (1950), nor in his contention that he is entitled to credit for custodial detention prior to his sentence in 1965. State v. Williams, 262 La. 769, 264 So.2d 638 (1972).
