RE: After watching the video IMO the reason he was shot in the back was because at the time he was half turned back discharging the taser.
I am not familiar with tasers. How dangerous is it to the officers from the distance he was discharging it from?
Who knows? They were fairly close. What if he disabled the cop and then grabbed his gun? These things escalate and get pretty fluid. Bad decisions can lead to bad endings. That’s what happened here.
