I don't know about the US but in the UK you are correct. In the UK unless you can unencrypt on demand of court its jail time - end of. I do not think this is obscure or unlikely. It is highly likely that paedophiles will use this network for instance and that somewhere on your computer you'll be storing fragments of child rape videos - a serious crime in itself. You will also be an accessory to the original crime.
