For some of our younger readers, Gov George Wallace predicted this in his statement "There will be anarchy in the streets" when you allow gangs to have free reign. Please don't take this as support of George, but that period of lawlessness was the forerunner.
One period was to make a statement for good and the other period simply causes chaos in the streets. This current bunch probably has no-vis and there is someone financing these activities when they are able to go across the country looking for the next cause. As long as local administrations support the cause, law enforcement is handicapped. Local ordinances have got to bar masking to conceal identities of the people involved with minimums in sentencing. And laws have to be rewritten protecting the rights of demonstrators. Difficult to curb when the law has to be on both sides.
