No not from nothing.
We have facts. We have a person shot in what people consider to be an injust way by a large majority of a community in St. Louis. We have people peacefully protesting the way the police department handled the entire situation. We have people breaking into businesses and other places and taking materials from these businesses.
If we look at it logically, which is why I used that word logic by the way, we can conclude that the two groups of people have different motives that may come from the same frustration or may not. However, there is nothing to be gained by the peaceful protesters in violently looting and destroying people's property. This will not change how the police handle these situations in the future which is something I'd assume they'd want.
I welcome discussion, but gotta say, you've been really dismissive and snarky and it's going to confuse the issue into a more ad hominem thing which I'm sure no one here really wants.
