So what is your logical solution in a situation like this where there aren't any handy independent witnesses to back up the police officers' claims? Perhaps the cops should surrender? Apologize and leave? Beg for their lives because shooting instead of being shot will incur accusations of murder from people like you?
Howabout some videotape evidence? If it's good enough for a traffic stop, surely it's good enough for a military-style raid on a citizen's home.
