Indy, glad to hear you are OK and I hope your dog recovers soon.
The real crime here is now you get to deal with all the hassels of the insurance paperwork, rental car, vet bills and time/money lost. The illegal gets a vacation, with three hot meals, a roof over his head, and a collage education to become a real criminal. When he gets out, he'll disapear and do it again to somebody else who may not get to be as lucky as you......only in the USA!
Just think, if you had physicaly restrained the guy, YOU would have been in the wrong, and you would have gone to jail, so backwards it just blows my mind.
If you were so inclined, one can look for the registed owner of the car that hit you, they can be held responsable for your losses.
