Yeah, waiting to catch the perp does generate some great conversations!
My best perp story was the OJ chase. My daughter was on a trip to the beach at a big party where all were drinking beer, probably illegally.
Someone ran in and turned on the tv for the chase and everyone crowded around. She asked what was happening and a kid said the police were chasing OJ. She didn't know who that was so shouted "we all better get out of here just in case they come here for OJ and catch us". It brought the house down.
