They both have a right to feel safe in public. We all do.
He was not just an innocent passerby or bird watcher like he claimed. He was harassing her because she had her dog off leash and was playing with her dog. In other words, he intruded upon her and she was right to feel harassed. His skin color has nothing to do with that.
His skin color has everything to do with her response though. Absolutely. Knowing Black people fear the police, she weapnized that on him. Nowz she may have meant it as an empty threat to start off with, to get him to go about his way and leave her alone. We won't ever know. But the minute she made that call, she set a sequence of events into motion that could have resulted in his death at the hands of an over militarized yahoo police force, she knew exactly what she was doing, and there was absokjtekt racial motivation.
They both harassed each other, disturbed the peace, were 50% in the wrong, and creates a shitstorm situation that didn't have to be.
They both bear the shame of that day, along with a whole lot of other folks.
My 2 cents. Things aren't always a polarized right and wrong. Sometimes everyone involved is wrong and it's just a clusterfuck.
