I'm not trying to argue,  but if the bodies he shot were lifeless,  how is that executing them?
Isn’t this the guy who robbed the store in Texas with a fake gun? >

Yes, only because he had trouble getting a real gun because of his many prior armed robbery convictions. >

Robbery, murder, domestic violence convictions.... >

Mannn the reddit lawyers are sure debating this one! I'm actually curious if a grand jury will bring charges tbh. >

I mean I don't know if you have seen the video, but it was more of an execution... >

I don't agree with that statement at all. Are you 100% sure the person who was shot wasn't going to turn around and open fire? Sure enough to bet your life and those of your loved ones? 
An execution would be if he disarmed the gunman, held him at gunpoint, and then shot him. What he did was shoot an armed robber who was still in possession of a weapon. The direction he was facing is irrelevant. >

He disarmed the robber. The robber was shot 8 times lying lifeless. He then shot an unarmed lifeless man in the head executing him.
