re: Atlanta Cops shoot man, I was wrong, it was justified

Well, I'm not so sure there's a solution per se. There are just too many potential factors and scenarios to come up with a "fix all". Like in this case there you could set up the exact same scenario in 10 different examples, but change one single thing in each one and there may well be 10 different ideal ways to respond to each.

Otherwise, the best thing I can think of is to at least try to get everyone on the same page as to the parameters of justifiable use of deadly force.
