Isn't that the area where the guy was beat nearly to death by asking the little darlins to stop fighting on his truck?
That attack was in a different part of the city by a different group of students acting like wild animals over near Dundalk right across the city-county line in the Harbor View/Graceland Park area. They shut that school down.
Neither of those wildings are isolated incidents either. They just happened to become newsworthy because they were caught on video. It's the same thing with the after-school flash mobs that rob and loot stores. Those wildings are ongoing.
