This is just not something I can really defend. I get it that you can't say this is a clear cut case of murder..... but.... I can't really defend this either.
An officer walked in the wrong house, and shot a law abiding citizen in his own house.
Now accident or not, this office caused the whole thing. This isn't a case where some guy runs at an officer, or tries to attack the officer and steal his gun, or refuses to submit to arrest and is choked to death, or has a realistic replica with the orange tip blacked out.
99 times out of a 100, I'll side with the officer, but this.... the officer just went into someone's home and shot someone. I just can't defend that.
You can say that "Well it was confusing, and not well marked" but again... as a person with responsibility, it's on you to make sure you are going in the right house.
And if what I read was true, that the officer in question had accidentally gone to the wrong house in the past.... then I'd think I would make even more effort to verify which apartment was mine, knowing that is a problem.
And additionally, knowing I had accidentally gone to the wrong home in the past, I would have thought twice when I opened the door and found strangers in that home. I would think... oh I must be at the wrong place. Not default to pulling a gun and shooting people.
So I want to give this officer a chance.... but I don't see it here. I don't see any reason to give the benefit of the doubt.
Obviously is there is more evidence than what I've read thus far, then I reserve the right to change my mind. But from what I see at this point... no, this is all on the officer.
