Ha! Robber dude said he would have shown mercy to a guy who had been shot and fallen down...fugg that. I would have kept shooting until the fugger didn't move! Did you see how the would-be robber was swinging the gun towards the old man as he started shooting?! How was the old dude suppose to know these dudes didn't have a loaded gun! Fugg that, they got what they deserved!
I agree, if I am ever in that situation I'm shooting until there is no more movement, or until the situation is 100% safe and I know that guy isn't going to be able to get a round off at me. I read more and more shootings even around here locally in the daily news, hopefully if more and more retaliations like this old man start happening, these scum bags will think twice.
