The homicide detective on our Tri-Team said we should have called 911...that really provoked my perspective.

If I swore out a complaint over the threat - he would have known our name/address. Hmmm

As it was, we were anonymous to him, but we had the benefit of his license plate #. Hmmm, that's what I call the "upper hand" as long as he doesn't go homicidal

I think I've reconciled myself to the difference between firmly holding your ground on something and being antagonistic. Holding your ground doesn't escalate a situation, but being antagonistic doesn't.
