Generally an accident is not a criminal matter, unless it's the Florida law about not leaving a gun accessible to a minor. It's a civil matter. The guy was hit in his leg, the video was released to the press by his lawyer.
All that seems to be a training issue, doesn't it? Though again, you're assuming that they harmed someone intentionally due to a failure to recognize a mental disability. I'm assuming it was an accident since they shot the guy on the ground in the leg.but as far as training goes - his finger shouldn't have been on a trigger in a first place. yet another example of just how absolutely abysmal police training is in this country. give them firearms, but don't train them how to use them. send them out into the streets, but don't teach them how to recognize the difference between aggression and mental disability or how to properly deal with either.
