Bryce Byron Larson appeals his conviction of a violation of the Uniform Controlled Substances Act (possession of cocaine), following a bench trial on stipulated facts. He contends the trial court erred in (1) refusing to require disclosure of a confidential informant's identity or hold an in camera hearing to decide whether such disclosure was necessary, (2) refusing to conduct an evidentiary hearing into probable cause for the issuance of a search warrant, (3) not requiring disclosure of all information about a heroin sale allegedly observed by the informant, and (4) refusing to find a violation of the "knock and announce" rule. We affirm.
