DWI is a crime of violence in that, 1)It is a crime, and 2)the effects of DWI tend to involve the use of force against another, or the reasonable expectation of force.
To illustrate: If Joe Critter decides that he doesn't like you, waits for you to step out of your house, and then accelerates to a speed of fifty mile an hour before striking you with the car, he has commited Aggravated Assault - you have suffered Death or Serious Bodily Injury by being struck with his car - ie., a crime of violence.
Now, if Joe Critter tries the above, but you jump out of the way, he has still committed a violent crime - you were in danger of suffering Death or Serious Bodily Injury.
See? The results of the crime include bodily injury and/or death, so the crime is a violent one.
Now, suppose Joe Critter drives to the top of a 50% slope and gets out of his pick-up, without setting the parking brake. The pick-up rolls down the grade and strikes a bus-load of nuns and the Vienna Boys Choir.
Is this a crime? Yes. Anybody with a lick of common sense knows that the vehicle was probably going to roll down the slope, unless reasonable precautions were taken and that stopping a multi-ton vehicle with your body ain't gonna be pretty.
Is it a violent crime? Yes. Death or bodily injury resulted, or could have resulted.
So. DWI. Crime? Yes.
Violent crime? Doesn't matter if the vehicle is purposely driven into a victim, or if the vehicle negligently hits the victim, or the drunk driver allows the vehicle to strike the victim, the end result is the same: death or bodily injury.
Reasonable expectation of death or bodily injury = Violent crime.
