Yes - This has been building for years
No - Individual cases will cool down.
I hate to admit this but there has been a lot of protests in America. This mayhem will continue.
You would think so, and I can't imagine that this will be allowed to continue for much longer, not destruction on this level.
I think it will calm down gradually, but police forces across the nation should be taking notes and reevaluating all officers and policies. We have to shrink the gap between police and public, or else more and more problems will arise.
