It's still declaring an intention to commit a crime either way though, isn't it? Unless you truly believe any prosecutorial organization wouldn't be able to crack the code.

Talking about it in jokes and codes just strikes me as either immature or ashamed, like how teenagers talk about sex or drugs. I think if they believe what they're doing is justified then they shouldn't be ashamed, and there's no reason to talk in code since that's definitely not protecting them one bit from any sort of legal action.
