Eventually it got to the point where the property owners began writing provisions into the rental agreements whereby the renter(s) would have to pay any fines associated with their troublemaking, and the only way the owner could guarantee payment would be to demand enough money up front (as part of the deposit) to cover the fine if necessary. When a bunch of young punks has to come up with a $10,000 or $20,000 deposit for a two-week rental, they either find somewhere else to go or they make sure they are on their best behavior.
That actually helped solve the problem. In that particular case any concerns about the property owner's rights weren't much of a factor, for a very important reason: Most of the owners of the rental properties lived out of town, and therefore had no say in the harsh measures the municipal government imposed.
Brilliant. Absolutely brilliant.
