Pilate tried three times to release Jesus and the people wouldn't have him. Finally, tragically, he caved in. He was clear that neither he nor Herod found any reason to condemn Jesus. Both found him innocent, but consented to his death nonetheless.
Interestingly, Herod and Pilate became friends. Two men with similar ambitions, lack of scruples, and common character discovered in each other a kindred spirit.
The specific accusations against Jesus were interesting -- he turned your people away, forbade them to pay taxes, saying Christ is king.
