enabling a crime: giving advice on how to avoid detection for a crime, advising someone of circumstances that would make it easy for them to commit a crime, when a reasonable person would conclude that your intent was that they'd go commit the crime and when they in fact went and did that; knowingly supplying someone with resources they needed to commit a crime; assuring someone of your intent to assist them in covering up a crime, even if you don't in fact assist them in covering up the crime.
