Gun training DERP

Here is a video from a police training site. There are so many testosterone laden idiots passing themselves off as firearms training experts, it simply makes me want to shake my head in disbelief. Is this REALLY what constitutes advanced police firearms training?

Why in the world would you ever need to train for an environment where you are in a gunfight with a disassembled pistol, a disabled arm, and wearing a gas mask? Seriously? This is simply pure stupidity, not to mention the multiple range safety violations.
