In the original thread I posted that it was overkill, and the Pharmacist deserved jail .
I stand by that now.
Basic rule of legal SD is shoot till the threat is gone, running after the armed robber indicates he thought the unarmed headshot robber was no longer a threat, same with walking past him to go get another gun.
If the assailant is down and no longer a threat you don't put 5 more into his head .
At least not on camera. What did he THINK would happen ?
