Let's place the blame sqaurly where it belongs and keep our eye on the ball. This goes all the way to the top. The great divider has driven a wedge in the country from the beginning of his Fundamental Transformation. This is but one more piece. I'm not saying he nor anyone else in the government has a hand in the killings, but the atmosphere of hate, unrest, tension and racial divide spews from this administration. The atmosphere for this to happen is part of his legacy.
Remember the cop that "acted stupidly"? He showed the world on TV how to disrespect LEOs. He's showed us how terror groups can target our military and LEOS in our cities, claim credit for it and not suffer any consequenses. He has validated the BLM movement with his comments. The list goes on.
Yep, I blame the guy who likes to use a good crisis to his advantage for the atmosphere for this sort of thing to even exist.
I support our law enforcement. I'm not sure what the answer is other than a change in atmosphere.
