Well- the husband IS a paramedic! There is nothing a paramedic can do to stop a stroke from happening. It was probably faster for him to drive to the hospital than to wait for an ambulance—or so he thought.
If he’d had 911 on the line while he was driving, he could have told them that he had a cop car following and for them to explain to the cop what was going on. Perhaps the cop would have wound up giving him an escort instead of arresting him.
