If it was a 'thing':
If I'd done it, I'd admit whatever it was and involve the cops.
If I hadn't done it, I'd tell them to do their worst and involve the cops.
If it involved a family member or friend and involving the cops = certain death for them...well, I, too, have a very particular set of skills.
(In that situation, you have to write off whoever they have and resign yourself to the fact that it's unlikely that you'll make it either. Anything more than that becomes a bonus so it frees you up. (I'm not eager to die but I'm not afraid of it, either. It's inevitable at some point, and why fear what must come?))
