In LA it is illegal to carry any kind of weapon on you. So the only people carrying weapons are the criminals.
Roger carries sex toys in his car. If the police stop him he is never asked about it. He is one many LA kali men who have now used a dildo as a cosh in a real fight.
Just imagine pulling one out of your pocket and switching it on at the start of a fight. Right up there with Eli pulling out his machete and reciting the bible. Makes the attacker think twice .
