You decide to bring up the cheque

“Your honor, If you see, there was a large cheque that was supposed to be for a Barrad Jack Flong, but simply never went through. When I had talked to the teller working at the time of the robbery, it became clear to me that this cheque was clearly meant to be a distraction, never meant to actually go through, just take the teller's eyes off of the things happening in front of them.”

The jury looks around, confused about what they just heard. You cut your losses and move on with the case.
