And I'd still like to know about the "American law" concept of "criminal facilitation."
"A person is guilty of criminal facilitation if he knowingly provides substantial assistance to a person intending to commit a felony, and that person, in fact, commits the crime contemplated, or a like or related felony, employing the assistance so provided."
You announce you want to break into Earl1972's house and steal his valuable collection of used Levrone posing trunks. [Work with me here. It's the dollar value that will make it a felony.]
I give you a copy of the key to his house.
You use that key to enter the house and steal the posing trunks.
Now of course, there is ordinarily nothing illegal about giving someone a key. But by giving you the key to Earl's house when I knew you wanted to rob it, I have criminally facilitated your act.
