Racing backwards... then voluntarily pulled over a block later, which I assume meant they went forward, while racing backwards. Yes, he wasn't a wizard, so shooting someone in a way that wouldn't just deter them, but kill the passenger, wasn't something he should have done. Knowing they were drunk and seeming to ram cop cars backwards, to end someone's life, would make him a wizard.
Yeah, I'm sure reachers will talk about how the cop was psychic, to know that a car moving backwards, that never ended up hitting anything, was going to ram police cars. It's a mater of psychic powers and not training. Nope, cannot be an issue with training... must be dealing with Xmen here...Dont worry the reachers here will claim the cop should have been psychic and known everyones life story in the car and curved the bullet to hit a crankshaft in the engine and stopped the car with no damage to anyone.
