Sounds like the cameras are working? Seems like a reason to put up more cameras: vandals can't take out any two as easily/simultaneously.
The legal system tends to react even more negatively to those directly attempting to undermine enforcement efforts - such as vandalizing cameras. You're not just doing "bad," you're constructively preventing evidence of your misdeeds from being gathered.
No, again that's easy enough to avoid.
But you're being obtuse on purpose (and ignoring the actual content of my very short comments) obviously because you want an argument, and this is waste of my time. Have a great life :)
