They don't understand it. By the Arthur C. Clarke rule, it's equivalent to magic. When you challenge the powerful, you are guilty purely because you did something the average unsophisticated user isn't capable of.
I've done far stranger, for far more questionable of reasons. Like the time I robbed a 7-11 at gunpoint for a pack of gum because a drunk told me he'd tell the world who I was if I didn't, and when I seemed interested in who he thought he was, he said he'd tell me if I did it. Except then he was gone when I got back, so I just returned the gum and fenced the gun and made a tidy 200 dollars.
