Oregon Protesters find HIDDEN “Goverment” Surveillance Cameras

Weatherproof/animal-proof cameras are very common. Just look at any Walmart store roof for example. So why disguise them?
Surveillance, infiltrators, etc.
But the really WRONG thing here is that they absolutely unnecessarily killed a man.
After looking at the video that was in the thread you linked I have concluded that you are in fact correct. These people were being very silly.
The Cameras are indeed attached to a pole that has multiple heavy conductors running to it. The Cameras are clearly marked as part of a SCADA (Supervisory Control and Data Acquisition) system.
What we have here are people who desperately want to believe there is a massive conspiracy controlling the government and that the government is intent on spying on them. (Like they couldn't do it with satellites.)
I am very familiar with the type. They imagine boogie men behind every bush. Nothing is what it seems, and everything points to government conspiracy.
They espouse a severe form of "confirmation bias." Everything they see is looked at in such a way as to confirm the theory that they already wish to believe.
This is the sort of hot-head, knee jerk, reactionary behavior that hurts rather than helps their cause.
