Could be true, but could also be false.
If Iran removes these cameras, they will have a much harder time tracking protests and dissidents.
So it's entirely possible this could be misinformation intended to mislead the regime into removing the cameras.
It would be simpler to put a disconect on the whole network, or you know, build a society that reflected how people actualy want to live. The unfortunate part is that cameras are hated everywhere, and EXACTLY the same people hacking Irans network, are running the ones in the US.
Oops I commented the same before reading yours.
