Let me ask a quick question

Let's say there is a set of Siamese twins. They have their own functioning brain and they just share legs. IF,one of them were to rob a bank and on the video footage and all eye witness accounts the other one was clearly not down with the shyt. He's telling the other one not to do it and he's screaming "I'm not a part of this shyt!!" How do they get sentenced? Do they have to go to jail? Would they go to some sort of hospital? House arrest? Alls I know is, if I was the "good" one, I'D.BE.PISSED.DA.PHUCK.OFF!

Weed is a helluva drug.
