Nobody is saying that police has to run away with the tail between their legs when facing a hard situation with non cooperative suspects.
Just saying that, there are efficient ways of subdueing, handcuffing and throwing someones sorry ass in the backseat of a police car, and absolutely retarded ways of throwing your career down the gutter, killing the suspect, and earning you a life sentence at a jail where everybody knows you are a former cop.
A different approach to a kind of daily situation for every mid size city police department around the world, suspect non cooperative when arrested, would have ended very differently. But here you have as per most reports, a whacko who shouldnt have been in the force in the first place as the most senior on scene with some rookies.... Open your eyes, Im only going to do it once...This is how its done!!!
Just my opinion
