This is not really a stand alone story. I recommend people do a little research. Check out Trumps' beginning executive orders especially the one setting the tone, direction, and basic framework for turning the USA into a police state with each and everyone of us within its jurisdiction. whitehouse.gov among other items has 5 pages of EO's. The order I am referring to was on Feb. 9, 2017.
"Presidential Executive Order on Preventing Violence Against Federal, State, Tribal, and Local Law Enforcement Officers". 
Sounds ok doesn't it? Well if you are willing to do some expanded reading and observing the trend coming out of Washington DC and you are a freedom loving American you may want to have heightened awareness. Just saying...
