I am not American though.
I've seen what they did to McAfee. His crime was avoiding his taxes. He got pwned in Spain. Died in a cell. I've never heard of a German guy that avoided his taxes getting pwned in the US by the German officers.
There were other examples too. Another one was the owner of btc-e. He got pwned in Greece... by the FEDs. How is that possible?
Yeah, McAffee had it coming.
On the other hand, Gottfrid Svartholm, Fredrik Neij, and Peter Sunde fought tooth and nail against the US justice system. After years lobbying the Swedish government, they finally filed charges against them, and they got arrested. They spent a few years in prison, and now they're free as birds, and nobody can touch them. And The Pirate Bay never got offline, and it's running today, stronger than ever.
In the meantime, the MPAA started a war against the Yify torrent site, and its owner, Yiftach Swery. They shut down the original site, and literally HUNDREDS of mirror sites popped up. Since, Swery retired, and Yify changed name to YTS. Still going strong.
Thank you all for the replies. Last night I realized I had been overcomplicating things. I don't need Tor, and chances are I don't need Tails (which is proving to be a pain in the rear to set up) either. If I'm running a wallet offline, I'm already safe. I'm thinking about using it together with a number of paper wallets, and I should be ok.
