Having my gun out while investigating a potential mugging in our company roomis a reasonable response in my eyes. I wish my friend had the part of the clip where we heard the restraints but unfortunately he does not.
The cops should have identified themselves or tried to deescalate instead of jumping to violence on, at best, an assumption I was involved. Cops should have a higher standard for using deadly force, especially when not looking like a cop in any way. The one who tried shooting me through the window did so when I was beside room 9, so one could reasonably assume I was going to that room as an alternative.
