I respect the pressure cops are under. I also believe it is imperative they be trained and held accountable to the job at hand. I do not understand the "shoot first, ask questions later" mentality. Seems like the smart thing to do would have been to, I don't know, run outside and call the cops. Where was he going to go? She could have arrested him when he exited the apartment ... guessing by then she would have figured out she was on the wrong floor and apologized profusely.
Not to chase a rabbit, but I think police since the 1980s have gotten way to militaristic and way to aggressive. I realize in many cases, they may be out-gunned, but it feels like some common sense is in order, i.e. serving warrants and arrests. Does not feel like the SWAT team needs to bust down doors every single time. Sometimes a cautious but polite knock on the door could de-escalate discrete and community violence and feelings between cops and the community. I get it is a chicken-egg argument, but I think generally cops over-reacted to the 1980s gang situation by moving from police work to military work. (realize it has been discussed ad nauseam).
