Well, how do you drive "defensively" when someone throws a couch on you. And you get a ticket. That story reminds me of an incident when i was a nurse at the psych hospital. Nonviolent patients were allowed to go for walks around the institution. Kevin went on a walk. His route took him by an ATM booth. You had to park, get out of your car and shut the door of a tiny room with the ATM machine. Unfortunately, Doug, stopped to get some cash. He left his car running and entered the booth. Along came Kevin, who saw a free car. He hopped in and attempted to drive away. Kevin didn't know how to drive a car. He sideswiped about six cars, before smashing into one. The cops came. Kevin had an air tight legal defense-he was a psychiatric patient. But Doug on the other hand, was given a ticket for leaving his vehicle unattended. Plus his car insurance company, refused to pay for the damage to the other seven cars, since Doug was blamed for causing it.
The moral of my little story is that life is unfair, and stupid stuff is going to happen.
