Getting parents to take responsibility for their ... children's actions is like getting people to take repsonsibile action with their pets, such as neuter, leave the @#$%& at home, or send them away from people. Same for the pets?
I had kids break every light in an old Subaru station wagon many years ago. We couldn't prove the kids that did the deed even though we knew. The worst battle was the insurance company. They only gave me junk yard pricing replacment on the lights. That was about 30% of actual value.
When's the next party?
