Legal or illegal doesn't really matter. If the regime wants to come for you they will.

I dont know. I think downloading it with Tor would make it almost impossible to find out you downloaded this stuff anyway.

Legality matters now least of all to either side.

Of course it's allowed. The gov will happily steal and buy all of your info. No problem to have it done to them.

You can't prove you didn't (and the fuzz will produce evidence you did).
