I don't know, i think the mentality here is that the government is spying for you, not at you. Is it different in the us? And is that because all revelations revolve around the fact that citizens are being spied on?
As someone who lives on the UK, I've never once seen a vandalised CCTV camera or even a vandalised road speed camera (which I'm given to understand is more common).
I've seen many of the early "Gatso[0]" cameras vandalised.
My understanding is that they originally used film, which had to be retrieved, so trying to burn it down with a well placed tyre had a chance of avoiding a fine.
