I am not trying to be callous about that situation, but it does not fit the bill of what we would be getting heavily involved with.

Nine times out of ten, you will not get away with playing games with the cops. That 10% of the time you will get away with gaming them, well OK, if you are well trained and prepped maybe 60% of the time, then you need to be on your game, and that also means not living with people who will call the cops on you, and not "getting crazy" when they show up.

Always deal with them like you are having to deal with an armed sociopathic maniac who knows he can get away with killing you.

There is a time to kick ass, and a time to take names, then settle the score later...

The big problem with that situation is the cops had been told the guy was an armed felon going nuts in a crowded apartment building. This was not an officer initiated contact like the beating death of James Chasse.
