When I was a kid our family just happened to be driving down the wrong road. Black thugs threw glass coke bottles and rocks through the windshields and windows of cars with white drivers. There were several families at the police station while we were there, I remember some had glass in their eyes and cuts. When the cops told my dad that they couldn’t do anything, my dad said he would go take care of the thugs himself. He was then told that they would have to put him in jail if he did anything.
And sadly nothing will happen to these new thugs.
Your Dad made just one mistake: He told the cops.
Nowadays people realize that they don’t have to do anything; everyone knows where “they” are, and all commerce has naturally migrated away to safer areas/neighborhoods (while you can completely avoid the “bad” areas). Urban blacks have been reduced to the status of “trading post Injuns”, dependent on the good graces of others for the most rudimentary existence while watching the world (and numerous incoming waves of immigrants) pass them by.
However violent Africa may seem at times, I must say that the people involved see a world in which they intend to play a part.
