It sounds like the police did a fairly rational thing here. They went to the house in a large group, they asked for the person, told him to out down his weapon, and didn’t shoot him. That sounds like a reasonable response, even though it ended in tragedy.

The only people responsible for this were the people who called the police with a false report. That is the crime.

I think cops do a lot of bad shit and need to be held accountable, but this sounds like they did the right thing.
