I can totally see the Parking Nazis ignoring the fact that someone is in the car when issuing a ticket. If the guy had been dead for a few days, that'd be different.
In the city of Trenton, Ontario, a few years back our car was ticketed while I was in the library. We'd put money in the meter and my dad had gone back out to the car about 5 or 10 minutes later because he wasn't feeling well. When I went out to the car, he was showing signs of a heart attack and I got him to the hospital immediately.
There was a parking ticket under the wiper that was written up with the time showing that not only had it supposedly been written while my dad was in the car, but they would have had to be fast runners because I was driving to the hospital at high speed at the documented moment.
It was fraud, plain and simple. My dad asked me not to pursue it because he wasn't up to going in to their offices to fight it.
The good news was that it wasn't a heart attack per se, no tissue death, but they kept him in the hospital for a few days.
