The problem here is one of propaganda that was fed into you since you were six.

"it is our cameras" "it is our police"

Neither are true.
They are owned and controlled by a corporation who all exist under a corporate umbrella called "The United States".

We don't go around saying AT&T security should protect us?

It is only our indoctrination that doesn't allow us to see this.
Those are THEIR cameras.
Those are THEIR police officers.
Those are THEIR lawyers and judges.
Those are THEIR news and disinformation services.

Yes, we are told that OUR taxes pay for it, but that is completely wrong. OUR taxes are thrown into a furnace. (yes, half of your wealth you create every year is thrown into furnace. just to keep you poor and hungry) And they just print more of THEIR currency to do whatever they want.
