Teachable for who? From the info provided, not the hotel guest. The cops, yes. Lots of unanswered questions. Warrant? What was the suspect wanted for? No mention of cops after a fleeing suspect?
Mr Little does not need teaching. The cops, well, I second the need for them to go purchase a lottery ticket. I wouldn't have believed a plain clothed individual claiming to be a cop at my door at night.
Teachable for the hotel guest also. He watched an uniformed guy break down his door and draw a gun and did not fire. In any number of other scenarios, he is dead or wounded. I can only assume the plain clothes officer was screaming that he was an LEO which is why he didn't fire.
As said above, I can't believe an LEO went through a torn down door without gun in hand.
