Even if the action was a crime, discussion about an illegal action, including instructions on how to do it, are not illegal. It might be illegal in very exact situations where you are giving information directly to a person you believe will use that information to commit a crime, but sharing the information in general as a topic of discussion is protected (at least in the US, laws do differ in other countries but I find the US law as the best one to go by).
