So they could defend themselves.
About the vehicle stuff, I just noticed today that even in the retail server non LE'd can shoot a LE'd player's vehicle but only when they aren't inside it, was 2.2 like this before all the volunteer team patches or is this a new bug? It seems strange to me, like the game isn't recognizing the vehicle as owned by a LE'd player until they're actually driving it.
I would be grateful if someone could make this clear for everyone.
