There were a whole bunch of articles a while ago about the rise of using SWAT teams for all sorts of arrests. Think from the officers' perspectives - they watch all these movies, they go and become FBI officers, and then they barely get to do anything exciting. So they naturally jump at the chance to do an exciting arrest. I guess there should be some kind of check-and-balance in place on the type of arrest, maybe for some arrests they should need to get a special warrant or something.
