Appellant appeals from the entry of a final stalking protective order of unlimited duration. ORS 30.866(1) (2001). 1 He argues that the evidence is not sufficient to support such an order under the requirements of the statute and, alternatively, that the order is too broad in scope because it does not take into account chance encounters between respondent and himself. We review de novo, giving deference to the trial court’s express and implicit credibility determinations. ORS 19.415(3) (2001); Pinkham v. Brubaker, 178 Or App 360, 362, 37 P3d 186 (2001). 2 After reviewing the record in this case, we affirm.

A detailed description of the facts in this case would not benefit the bench or bar. In our view, the first assignment of error turns on whether, as respondent testified, appellant pointed or waved a gun at her or whether appellant, as he testified, placed an unloaded gun on a bed and suggested that respondent “finish [him] off’ in an act of histrionics. In light of the trial court’s ruling, it must have believed the former. Because the trial court had the opportunity to view the witnesses firsthand, we defer to its finding.

The second assignment of error was not preserved in the trial court. We therefore decline to review it on appeal. ORAP 5.45(4)(a).

Affirmed.
