Is it impossible - or far more likely obscenely difficult - to track down someone posting to UseNet with SSL encryption? Anyone around here that's poked around the newsgroups is probably aware of the blatant illegality of some of the posts. I've seen plenty of headers listing, without euphemism, child porn and alt.suicide.methods is interesting to say the least.
Could the police force theoretically get some IPs if they devoted enough resources, or is it just impossible?
May the source be with you.
