FBI agents killed Randy Weaver's wife and son at Ruby Ridge. If you think a Cop won't violently kill someone who doesn't deserve then I disagree.

Kinda hard to remove yourself from a situation when they are literally circling around the block and on the look out from you. It's a timebomb waiting to happen and they need to feel some pressure from a judge and laywer to deescalate. But who knows when that can materialize, so in the meantime they need to prepare for the possibility that this guy isn't all bluster.
