I saw this in a different thread. I had not heard of it before.
Thought it would be best to put up a thread on it. Something people need to be aware of for personal safety if they visit certain areas.
Hopefully the authorities will put a stop to this sort of nonsense quickly.
Apparently it has happened in Philadelphia, New York, and some other cities.
Three Knockout Attacks Reported In Philadelphia Area
A few stiff prison sentences will probably put a stop to it pretty quickly!
Philadelphia and some other cities had a similar problem with so called Flash Mob violence and crime a couple of years ago. It often involved mob of younger people (some kids) attacking people, robbing stores of goods, etc.
