The '80s and '90s had a plethora of comedies that were basically what-if-this-happened stories. In addition to the ones with a fantasy element (Ghostbusters, Bill & Ted), there were earthbound ones with nonetheless improbable story lines. A notable one was "Weekend at Bernie's". A lesser known one was "Men at Work".
Real-life brothers Emilio Estevez and Charlie Sheen play garbage collectors who discover a dead body. Sure enough, the situation soon snowballs (I like it in comedies when more and more people get drug into the story). The whole movie is pretty much an excuse for a bunch of silly stuff, namely the pranks that the guys play on some co-workers. I suspect that everyone had fun making the movie. True, the gay jokes have aged poorly, but other than that, it's funny.
I'd say that after the events of the past few years, anyone would be justified in distrusting the police.
