Big D, couldnt keeping him stay put by intimidation untill LEO arrived be considered "False imprisonment?". (I am twice his size, but more than twice his age too.)
Years ago I was in Los Angeles with a girl friend. She was driveing my car, a 1964 coupe deville. I only had liability on it as it wasnt my main ride. A drunk pulled right out of a bar and T-boned us. They took off, the GF stopped. I yelled for her to follow them as I wanted a license # and knew I was SOL with my insurance without it.
That was like turning police woman angie dickinson loose! She boxed them up in a parking building just like you seen on TV 50 times! They delibertly smashed into us about 3 more times trying to force us backwards to get away. As I was getting out of the car I grabbed my S&W model 60. In a rage I knocked the driver down when he challanged me. I held both while the GF drove off looking for help.
Long story, short, I wasnt arrested, was given my gun & ammo back. However this was about 35 years ago, and it probley helped me that there were warrants out for the driver etc. I am sure I would never get away with that again, especialy in Los Angeles!
Anyway, I always have been lucky in that type stuff, Thanks!
