Okay, we have a small parking lot for faculty & staff here at the law school, so I understand why the parking enforcement people are constantly checking permits and giving tickets. Tickets deter unauthorized parking and generate revenue. But when you have someone who doesn't respond to the tickets, something else has to be done.
But really, the boot? That doesn't seem like the best idea in a small parking lot, since that's one fewer space available until the bootee shows up to pay accumulated tickets, etc. It seems to me that towing would be a better step of escalation.
