RICO= Racketeer Influended Corrupt Organizations, you're NOT going to be prosecuted under a RICO statute for telling someone about a source, I assure you. It will take more of an active involvement than that.
I could say, rob a bank to support your cycles, that does not make me a coconspirator really, if you go ahead and do that. Someone's free will is usally a complete intervention in liability of any kind.
