Tommy Boy, I don't know what you are basing your view on but you may want to expand your sources of information.
The media, the entertainment industry, academia, large segments of social media and left wing political operatives - all falsely portray American Law Enforcement in a negative light.
It is very easy to get a warped perspective. I don't look at all U.S. Army soldiers as Nidal Hasan, Timothy McVeigh or Bradley (now Chelsea) Manning.
I don't look at all doctors as Larry Nassar or all FBI agents as Robert Hanssen.
Bad actors get the press but they hardly represent the norm.
There are well over 725,000 Federal, State and local law enforcement officers in the U.S.A. Considering a population of well over 328 Million people, the huge geographical size of the U.S.A. and the need for 24 hour a day/7 day and week coverage; that's a remarkably small number of officers. Very, very few officers ever dishonor their profession. You would never know that from watching the news or listening to the liberal rhetoric that is pervasive in our society.
So without getting political, I'll say that Officer Sean Collier, killed by the Boston Marathon bombers or Officer Eric Talley killed just a few weeks ago in Bolder, Colorado don't get the attention of the liberals because those stories don't fit the liberal narrative.
