I actually doubt that the guy could have gone another 8 to 10 miles to make it to the Vet in time. Sure he could get through the front door if he was going 100 miles per hour which he was, but what if the Vet was busy with another guy who came in or the dog just died anyway? Sure the vet was talking to him on the phone, but whos to say? Besides, those Big Rigs looked dangerous.
The cop is still an asswipe though. This is pretty much how it happened:
"Calm down, calm down"
"MY F^%$%ing dog is dying you ass!"
"Calm down, show me your drivers liscense, oh im sorry this is not your liscense, lets wait for 20 minutes while i write a ticket up for you while your dog dies a miserable death. You can always get another dog. Relax."
