Are you willing to potentially be prosecuted to make a point that will ultimately come down to, "The cameras you destroyed are replaced with newly purchased units"?
The way to beat this isn't vandalism, it's getting them banned from every municipality and county in the country, while fighting at state levels for more bans.
It's also silly talk from kids online, just like "Don't vote, burn your local Wal-Mart" is only meant to impress other online children. The rest of us know that you'll neither vote, nor burn down the Wal-Mart.
I can't speak for anyone else, but I suspect most terminally ill people want to spend time with the people they love, not breaking cameras and working their way through the legal system.
