How to protect yourself in during a South Street Flash Mob

We have all been witnessing an increase in random violence.  Just this past weekend I saw mulitply news reports about Flash Mobs in South Street Philadelphia PA.  What is a normal law biding citizen supposed to do to protect themselves?  Not everyone wants to carry a gun, and what would you do if you were surrounded by muliply attackers?  We have just launched the Tornado Personal Defense System at Xfighterdefense.com.  This product incorporates a personal alarm, flashlight, and 6 seconds of blinding pepper spray.  This defense system can help you feel safe in this uncertain time.
