I have scanner apps on my iPod touch. Unfortunately, my local area isn't on there, but I'm in a neighborhood Facebook group, and get all the happenings that way. There are always people posting about trespassers, thefts, loud noises, loose dogs, etc., which is nice. I used to have an actual police scanner, and loved listening to it. I turned someone in that way before. I had just seen him on my way home, got home and turned scanner on, heard he was being sought, so called the local police and told them where he was, and listened while he was apprehended. I also happened to be listening one day, when I heard an ambulance being dispatched to a friend's house. I found out later that she'd made chicken soup and had forgotten to strain it, and her hubby choked on a bone. He survived via the Heimlich, FYI.
