Ive responded to more fatality crashes due to intoxicated driving (killing pedestrians or other drivers), than I have with gun-related murders (and I go to 1 at least once a week). Last night I had a head-on collision that killed 3 people because a drunk driver fell asleep at the wheel (guess who didn't die? The drunk driver).
Vehicular homicide is more of a problem than gun-related murders. (roughly half of the gun-related killings are suicides, not person to person)
I think this ^^ is more of a problem.
