Robert 'Bob' Kirkland is an accomplice of Red John

Jane is MORE clever than Red John and knew something would happen to his list so he planted a fake list knowing someone would take it and whoever takes it IS an accomplice of Red John.
Jane wanted someone to take the list so Red John would feel safe because he would know he is not on the list.

This is why Jane was smiling when he saw the toothpick on the floor because he then realised someone had broke in and his plan is now in motion.
