The fact that it is a lawyer who did it makes things even more pointed.

If you were the judge, how would you sentence?

....to get back at dirvers who don't bother to park properly.

I have an older pick-up truck so a door ding or scratch isn't a big deal to me on this vehicle.  When I'm in my truck and see someone over the line in a spot that happens to be on the driver's side, I pull in the adjacent space with my passenger side just inches from their car and hope they come out before I do.  There are few cars today with a full bench seat in the front so the driver has no choice but to climb over their console to get behind the wheel.

I understand the Seattle guy's frustration but he should have stoped at leaving the nasty note.  Keying cars or letting air out of tires goes over the line.  Plus, at 63 years old he's lucky he didn't get caught in the act by some big young dude .

hogging the extra space and clearly included their license plate, then posted them on a "Parking Hall of Shame" website and forwarded a copy to the company that manages the facility. Damn, I might have to start parking in one of those ramps just so I can use that idea!

fact is that unless you observe a driver park you don't know the whole story.  Often in garages with very limited parking there will be no open spaces, and the one open spots may be a situation where the car already in the adjacent space is straddling the line, forcing me to pull in and straddle the line on the opposite side just to find parking and/or to allow that already straddling driver room to access his/her door. Also, many of the garages have spaces that are just too narrow - I drive a big pickup, its wide, and if the spaces are too narrow, I have to straddle just to park - that's the fault of the parking lot designer who designed spaces too narrow.  Unless you know the full story, I would not jump to blame the vehicle you happen to find straddling a line - it may not be their fault.
