A lot of cops have been hurt or killed by getting in the middle of a DV, with and without appropriate amounts of backup. A situation like this, only in a apartment, almost cost me my life and career. It's complacency and/or a hero mentality overriding common sense.
One of the big qualifying questions in this scenario has been missed up to this point. Is anyone in the car with me?
What about utilizing the car as a tool?
Regardless of the answer to the having company question, is there anything wrong with just hanging up the gas pump, getting in the car, and using technology to put a lot of distance between you and the problem? Even if you're going to just be a good witness, what's wrong with moving the car to the other side of the parking lot, leaving the engine running and in gear, and having the car angled towards an escape route?
