Blue Streak

Lawrence and his cohorts are in the midst of a diamond heist when he's nabbed by the cops on a nearby construction site. Reluctant to be collared redhanded, he hides the hot rock in a ventilation duct, resolving to return and retrieve it. After a two-year stretch, he looks up the old address and discovers it's LA's largest police station. Posing as a pizza delivery boy doesn't get him past the front desk, but when he comes up with convincing ID to pass as a newly transferred detective, he's in. None of this is within hailing distance of plausibility, but it does make a certain skewed sense that the crook's streetwise nous is what makes him a successful, if unconventional cop. The conceit is fun, but the movie doesn't give Lawrence anything challenging to do.
