I think South Carolina has had a problem. Myrtle Beach had at least one incident. Charlotte, Boston and a few other places had them all at the same time. There was concern that they were coordinated attacks.
Sadly, the gangs may be using Facebook, Twitter, and cell phones to coordinate their flash mobs.
What do we as a society do if civilized behavior breaks down in our big cities?
It’s one thing to see ghettos in which civilization has deteriorated, but what about when entire cities or regions become infected?
Should we all move to small town or rural America? Move to an island somewhere?
If entire cities are going to go ghetto, where will we be able to escape to?
What you have at Myrtle Beach are two biker weekends, one white (mostly) and one black. The latter has been marked by trashings, drugs and violence for so long that local merchants shutter their businesses and declare a general strike whenever it rolls around. It does not appear to be part of the sudden current urban epidemic.
The use of social media could exacerbate things at Myrtle Beach as it has elsewhere, though.
