You’re driving through downtown Philadelphia. It is almost 9 at night. A car pulls up beside you at a stoplight. The man in the car points a gun at you and says to get out of your car. You own a handgun. You have your Pennsylvania license to carry. You’re armed tonight. You pretend to move the seat belt as you draw your firearm. Your attacker is getting out of his car when you shoot him. He drops his gun so you drive away and call 911. Police find your attackers. The police call for EMS to transport the wounded robber to the hospital. The police arrest your attacker’s brother as the getaway driver. The two of them had robbed another driver at gunpoint only a few hours earlier and were sitting in the stolen car. The police said they have surveillance video of both attacks.
