There are plenty of incidents where the police officer overreacted or had a bad attitude even if he did not use a taser. Many police agencies definitely need to improve discipline and hire a better quality of recruit. For example, it is ludicrous that a newly hired policeman in New York City makes a lower salary than an assistant manager of a fast food restaurant. That being said, it is also true that the rash of anti-LEO sentiment is very reminiscent of the attacks against police brutality 40 years ago. Every time a cop used a nightstick or a choke hold on a suspect, he became a mini-version of Bull Connor. The liberal print media and TV network publicized alleged abuses to the point that the public voted liberal politicians into office who appointed judges that routinely threw out legitimate cases on technicalities and who severely tied the hands of law enforcement.
In the 1950s and 1960s, there were a considerable number of racist lawmen, as there are LEOs today who are not reluctant to assert "authoritah". However, the reaction, this time fueled not by the print media and TV, but by blogs and You Tube (the confrontation involving a young motorist and a Utah state trooper was viewed over a million times), may wind up interfering with legitimate law enforcement and causing a weakening of public order. I do not think it is the Muslims, but the Left, and their useful idiot friends among libertarians and conspiracists, who are behind the attack.
