Vandalized mailbox and circuit breakers

[Hernan B.]

I seem to have kids in my 4 unit building that continue to turn off circuit breakers in the basement (making some of the tenants appliances turn off and spoil food), vandalize the mailbox, and create problems. I have an idea its kids from a certain unit, however, I am not certain, in fact I am not certain its kids at all. Any suggestions? I feel if get a new mailbox it will just get destroyed again. I just got fire extinguishers for the building and they are already empty within two weeks of getting them. Do I want to lock off the area of the basement that contains the circuit breakers or just give the unit whose kids I think it is a 28 day notice (they are month to month). Are cameras worth having or will they just be vandalized as well? Let me know if anyone has suggestions
