The blood draw would never have stood up in court, the officer and lt would have been probably reprimanded but the nurse would have been fired, possibly have lost her license and may have faced fines, imprisonment plus civil penalties as the cherry on top.
The hospital would have also faced fines and civil penalties.
This is why they were careful to have everything written out in a contract with the police department.
But I don't think the blood draw was ever meant for court. Even if they had gotten a warrant the truck driver had already been treated for burns which would have involved drugging him. I think it was to try to pressure the truck driver to not go after the police department for his injuries. They would have hinted to the papers that drugs had been found in his system.
It would have ruined the truck driver's life but it would have gotten the police off the hook in the court of public opinion.
“Even if they had gotten a warrant the truck driver had already been treated for burns which would have involved drugging him.”
They could have been looking for THC, cocaine, heroin metabolites which would not be something that the hospital would give to sedate a burn victim. Cocaine and heroin don’t last very long as metabolites which might have prompted the rapid “need” for the test.
This appears to be very slimy police CYA operation.
