On the other hand, cops here in Austria saved my life a few years ago. A very drunk guy parked his car in my driveway, so i called the cops. They showed up, and the drunkard pulled out a gun - in the blink of an eye the cop next to me shoved me aside to safety, while the other one had already pulled the guy out and took his gun.
I guess without the same "standard procedure" that happened to you, i might not be alive today, because the drunkard had a full magazine (and as i was to learn later, was already known to the police for all kinds of stuff).
So i wouldn't take it personally on how the cops did their job. It's how they are trained, how they keep beeing alive when dealing with (potentially) violent persons.
