How does disagreement with police actions or court decisions transition to, "Let's riot, loot and destroy our city?"

There was 1 mother out there beating on her son doing wrong. For this conversation only, I submit..

Make absolutely no mistake. People committed to social change organize, protest and raise awareness. These are the actions of criminals, who if they get caught, will claim that the man made him crazy. If there were businesses and more job opportunities available and grocery stores instead of corner markets there would still be drug dealing scum and people who are empowered to sit on their butt out of the sense of entitlement that comes with being a spoiled American. Need money, make babies. Don't get married, it will take away your food stamps. Have 6 kids with 6 women, don't pay child support brag about how many shorties you have. Get a criminal record for breaking the law and then complain that you can't get ahead in life, join the military, or go to college. Cut all your avenues of escape out of the cess pool you live in and then burn it down in the name of...........being a victim. I was so poor growing up I'm embarrassed to talk about it and joined the military so I could have a roof over my head and escape the crap hole I knew. All my "friends" are dead now. The last one died a couple months ago. I NEVER and I mean NEVER burnt down Philadelphia. I did go watch Osage Ave burn down when those MOVE members challenged the cops to a throw down, but I digress. What kept me out of trouble? Knowing that if I got out of line at home I was through. Am I saying beat your kids and put cigarettes out on them? HELL NO! But lay down the law! You are home at 6pm for dinner. You are going to complete high school. If you are getting in trouble with your "friends" I will lock you down until there is no more trouble. I will stay on you until so that you respect your elders from the get go. If you don't work a legit job I will find you legit work to do for free helping others. ETC,ETC,ETC.......

I have been on the receiving end of the Los Angeles Riots (1965, 1992), Jalalabad, Afghanistan 2005 Quran burning riots, Parwan, Afghanistan 2006 riots, all I can say is that humans and easily be manipulated to being stupid and breaking laws. But kudos to the Mother seen slapping her teen age son who she caught involved in the Baltimore riots. We need more mothers like her.
