LEO doesn't like the competition; bikers are making them look bad. Bikers are America's largest demographic of pure patriots, whether they're riding a million strong on Washington DC in 2013 to protest 9-11, or standing up against flag-burning commies in NYC who otherwise perceive silence as consent. REAL bikers (as opposed to Sons of Anarchy fictional bikers) are patriots who love their country and are doing something to preserve it.
The leftists in government fear those patriots and have come up with a way to "legally" destroy them even if they have never committed a crime -- see May 17, Twin Peaks, Waco, Texas.
LE indeed has a lot of explaining to do for Waco 5/17/15. The DA, Abel Reyna, has a whole lot as well.
I am interested in both, but at this point, more so in Reyna. His known connections and alliances are, uh, interesting.
