Welcome to the "high cost of crime." Now you can see how you lose money even when nothng is stolen.
While copper prices may be a factor, the nature of these crimes suggest that trades people are involved. On a small scale, such crime has a word for it: Meth. On a larger scale, we have seen organised gangs, equiped with heavy equipment, strip job sites on weekends.
Ultimately, the solution goes beyond buying better locks.
