Riots in the Streets of the USA

There is a reason why many American cities have erupted in violence over the past couple of weeks. The obvious reason that everyone knows but no one wants to acknowledge is that minority citizens of the USA, but especially black citizens, are being singled out by law enforcement and brutalized while they are in police custody to the extent that they are dying unnecessarily. WHEN IS THIS GOING TO STOP??? As a citizen of these United States for over half a century I have been a witness to this tragic state of affairs for as long as I can remember. It is not what I want to think of when I think of the USA but it just goes on and On and ON!! How can we possibly explain this to our children and grandchildren?? Is it any wonder that they no longer want to live in a country where police violence is causing black people to die unnecessarily and where the police are not being held accountable for their crimes? I say ENOUGH!!!!
