I think this is awesome. We need to see more videos like this where law abiding, legally armed citizens turn the tables on these thugs. I know they're saying it's likely no charges will be filed, but was he really justified to pursue and shoot the fleeing robbers in the back? By law, isn't your right to use lethal force stopped the moment your target turns and retreats, or as in this case, runs and trips all over each other? In fact, from what I saw, all of his shots were in the back. Of course, if I was in his shoes, I would have waited until the guy turned around before attempting to draw and act. I think the first shot was justified, even if in the back, because he felt others were in danger from the armed perps. But, after the first shot, both perps started high tailing it out of there, and the guy kept chasing and shooting. I hope this doesn't bite him in the rear.
As a side note, I'm also thankful he didn't shoot anybody else. His one-armed shooting while chasing the perps wasn't ideal.
