I'm personally aware of a fellow Narc who tried to extract a suspect through the side window of a car. Step one was trying to break the window with his 2 1/2" 66. The window didn't break but it did bend the trigger guard bent so much that it blocked the trigger. I wasn't at the scene but handled the revolver later. The trigger guard was mashed in enough to physically prevent pulling the trigger.
Fortunately, the turd was convinced of the seriousness of his situation and decided to give up without a gunfight.
