Where I work ALL INTERACTIONS with customers are both monitored and recorded to ensure quality control.
Look, guy #1 had a knife and attacked guy #2 who was defending the woman in the apartment. The cops showed up and guy #2 headed out of the apartment. The cops verbally engaged guy #1. Guy #2 ran back into the apartment and tussled with guy #1 again. The cops tried to shoot guy #1 but, in the process, got guy #2 as well. Sucks that it happened but guy #2 was a total dumb ass for running back into the apartment.
