A lot of that is due to those being the only sources covering those stories. Some dude in a MAGA hat can shoot a deer out of season and he's a Proud Boy right wing extremist evangelical who recently purchased enough ammo for a couple of hours at the range and posted memes on Facebook that make fun of Obama.
Meanwhile a minority can run over a Capitol Police officer and that cop was killed by a car.
I've seen those individuals you listed post videos of groups of BLM protesters beating individuals, dragging others out of their cars, tossing bricks at cars passing by.
USA Today and the alphabet networks don't find that newsworthy for some reason.
