I carry a 9 mm routinely. I also carry a small audio recorder that makes a digital recording of the local sound. The thing is small (1" x 4" x 3/4"), cheap ($80), and records 16 hrs - Olympus VN-960PC. It is reliable. The point is - if I run into someone who attempts armed robbery on me, and I end up shooting him, the recording could help in my defense. I may record him speak some threat against my life. I was walking in my neighborhood not long ago, and some yokel was walking his two dogs off leash. One of them, about 80 lbs, approached to a few feet away and was growling and had his hackles up when the owner said, "Get him." My hand went to my hip, under my shirt, but I did not draw. The owner/moron said he was kidding; that the dog was friendly. If I had quickly shot that dog, then the recording would have helped to prove that I was in reasonable fear of serious bodily injury. What are your thoughts on routinely carrying a little recorder in the pocket, to remove the my word vs. your word problem in a shooting?
