It's maybe important to note that the phrase 'He was no angel' is a common (extremely dark and sarcastic) joke in left-leaning circles around these kind of tragic murders because there is always, without fail, some right-wing effort to paint the victim as some sort of low-life who had it coming one way or the other.

Let's be clear: no one, regardless of how much they've fucked up in their lives, deserves to be murdered in cold blood by the police while they pose no threat to anyone.

To restate: a non-violent suspect's past offenses are not germane when the discussion is about the police summarily executing that non-violent suspect in the street.

Any attempt to confuse this point with ideas about how the victim wasn't perfect, about how they could have done better in the confrontation or not committed a crime in the first place, is an attempt to deflect blame onto the victim.

These kinds of arguments are prima facie disgusting and deserve no quarter in civilized discourse.
