If you aren't going to deal with the vandalism, then it's your problem.

Yes. And?

Did you have a suggestion of how to do that effectively without
suffering an accidental fire, accidental smashed window, etc likely
to be meted out by these guys if I haul them into court?

Do you have some better information about the motivation for the
vandalism than I've conjectured here so that I can make it more
valuable for them to dump elsewhere?

Thanks!
