No he wasn't a felon. The driver of that truck was working when the driver of that car, in a high speed chase with police, veered into oncoming traffic and hit the truck head-on. The driver of that truck was working safely and did nothing wrong. The police knew they were in big trouble, liable for his career ending injuries and brain damage (He's in a coma). So they went to get his blood in hopes they could find something like Prozac or Marijuana so that the police would be exonerated. Pure fishing expedition and highly illegal search and seizure.
