You say that we have created a system where police officers can kill with impunity and law-abiding citizens have real fear of being killed by police. I agree with you. I'd say that this is pretty much common knowledge at this point. Which means that everyone should know that if you get the police to respond to what they think is a life-or-death situation, a killing by the police is a likely outcome. I.e. given what you describe, the caller should reasonably expect that the police would kill an innocent person based on their false report. The correct response here is to prosecute the SWATter for murder, and carry out the police reforms you mention. I don't object to the second in any way, I merely object to the diminishment of responsibility for the guy who made the call.
