Man jailed for parole violations after refusing to decrypt his Tor node

I certainly sympathise, but actually don't find it at all surprising.

Tor is totally used for criminal activity. That doesn't mean it is inherently a bad thing, or that it is this guy's fault, but he can't completely wash his hands off it. If bad guys use the postal service, it's not the postman's fault, but he has to cooperate with law enforcement if they demand that.

I don't know about the US, but contempt of court is a thing in the UK at least. You can't refuse to submit evidence to court, including things like encryption keys or things only stored in your head - or face penalties including unlimited jail time.

Now, I get that this is the US so the arrest was dialled up to 11 and it seems all of this is extra-judicial - no court warrant etc. This is all very disappointing. But, to my non-expert eye running a Tor exit node is in the legal grey zone, and I guess you can't be too surprised when things like this happen.

In the U.S. and much of the rest of the civilized world, you have rights. This includes the right to not self-incriminate (in the U.S. that's the 5th amendment). In general, except for very specific and limited circumstances, U.S. state and federal government actors cannot compel speech (telling your encryption keys is compelled speech).

The U.K. is fast sliding down the slope to being a dystopian police state. The idea that you can be jailed for refusing to provide encryption keys (except for really specific, narrowly-defined circumstances) is something that should induce nausea. I feel for you and your country, you accomplished such great things.
