If you drive a cab or operate a ride share vehicle, there’s always a risk. You never know who’s getting in the back of your car or what’s on their mind. Uber and Lyft have policies preventing their drivers from carrying firearms, but a lot of their drivers ignore that prohibition in favor of being able to defend themselves.

On Wednesday, a Duquesne, Pennsylvania jitney driver picked up a couple at about 3:000m.

(Crosby) Marshall said he had picked up the man and a female passenger minutes earlier. He said he knew something was wrong when the man began sending him along an alley, then suddenly told him to stop his SUV. “I turned around when he said he was going to rob me, then he hit me with the gun,” said Marshall.

That’s when Marshall tried to get away, but the man with the gun came after him. Fortunately, Marshall is a licensed concealed carrier.

Marshall said that while bleeding, he managed to get out of the car. He said the female passenger ran, and the man got out, too. Marshall said the man was pointing a gun at him. “I was backed in a corner,” said Marshall. That’s when he said he fired his weapon. Police say Marshall fired three times, killing the man. They said Marshall had a permit to carry the firearm and is not charged. “I just had to do what I had to do,” said Marshall. “I’m just happy to be here.”

Marshall hasn’t been charged and, given the fact that the 73-year-old had a permit and was clearly defending himself, likely won’t be. Another life saved thanks to the timely use of a gun in a defensive situation.
