cracked butt beat me too it. (That just sounds wrong on so many levels. Anyway.)
There is more to threat identification than simply visual cues. Sounds and smells should also be used. The only cue he had was auditory and Captain Mike reacted like I hope I would in a similar situation. The only possible critique I could add would be the direction the muzzle was pointed when he visually tried to figure out what was going on but either way I would consider it well done.
As for the whole profiling charges, if that's what he did I would have to say, "Holy cow, he must be human." Profiling is what has kept man alive all these years. We profile bright red cirles on a stove top, we profile snakes that make rattling noises when they shake their tails, and the list goes on and on. If I were in that situation and I noticed guys that look like thugs, gangbangers, goth, whatever, they are going to register in my mind as not conforming to societal norms which means they get the most attention. Though you may be offended in the end, it's kept me alive and I'll stick with it. Looks like a duck, quacks like a duck, then to me it's a duck and not some goose trying to stand out and get attention.
