it's not my opinion it's the opinion of the investigation that he did not run. established as fact.
"Whether or not he was a threat, again, for the purposes of murder, is not relevant, it is that they believed him to be one." i could say that about anyone. "i thought he was going to rob me" "did he look like he was going to" "no but he lives in the same area i think folk do some robbing" "so you shot him?" "yes" "well that's okay then"
there was no reason to suspect him. and that is the point.
armed police are only allowed to shoot if they feel they or the public are endangered. what reason did they have to believe that?
