"People with medical emergencies should run from the police? "
Perhaps he had a passenger who was dying and needed immediate medical attention. Perhaps he had ingested a large amount of poison and was rushing to the hospital. Perhaps he had a family member who had been involved in a terrible accident and needed a rare blood transfusion / organ transplant. Perhaps he was just imagining one or more of these things.
"Mentally unstable people probably shouldn't be driving."
And police shouldn't be kicking people's teeth in...
"Back to OJ...he had a gun and he's my friend so I had to do it?"
If you're in a car and a guy is holding a gun to your head and says "drive", then I fail to see how you're breaking any laws by doing what you have to do to stay alive. Maybe the guy thought somebody was there with a gun to his head.
"And you saved the best for last...did you make that up...or can you post an actual story?"
I just made it up, but reality is stranger than fiction. Do you think that a police officer somewhere in America has never threatened to kill somebody and actually done it, making it look like a legitimate police action? I wouldn't take that bet, and I doubt you would either.
Drugs put funny ideas into people's heads. If the guy was hallucinating, or had a reason to run, he doesn't deserve to get kicked. He has the right to tell his side of the story. That's what the court system is for.
