Is the policeman who killed an unarmed man at his house going to be charged? Ideally this wouldn't be a rhetorical question. How long until the police give themselves the right to kill someone annoying by anonymously phoning in a warning then making sure they're amongst the ones who turn up?
This was my immediate reaction. My guess is that the blame and punishment will all be laser focused on the caller, in an attempt to avoid a public outcry for the actual shooter’s head. That cop shouldn’t be on administrative leave, he should be in jail for murder.
I do agree with you, though, that a close look should be taken at the shooter and the situation with an eye toward possibly charging the shooter. I do think that in general, police in many parts of the US are too insulated from the consequences of such decisions. I'm not completely sure, though, based on this article, that I would consider the officer culpable. Police are trained to react quickly and to protect one another. The description here does leave me with the sense, however, that the one who fired may not have had a particularly good view of what the victim was doing. Arguably there is a systemic problem that when there are many officers, all with different and incomplete views of the situation, the odds of one thinking that something is going on that justifies opening fire get to be unacceptably high.
Anyway I do hope you're not suggesting that the shooter's responsibility somehow mitigates that of the caller.
ETA: Ah, I didn't know there was body cam footage we could see [1]. Okay, I have to agree with you, this looks pretty damning. There were no officers within easy target range of the victim; the shot was taken from well across the street. Even if the victim had been pulling out a gun, unless he's a Clint Eastwood character, he's going to have to take a second or two to aim it to have any chance of hitting anyone at that distance. It was not necessary to fire that quickly. I have to qualify this by saying I'm no firearms expert, but that's how it looks to me.
