While they may not have listed every criminal (well, they did note the most nortorious ones), there is no record that they had ever had a tradition to release a Jewish prisoner on Passover, and the Christian texts calls it a normal thing. The Jews make no mention of such a thing ever happening (they do list the horrible things that Pilate did), nor do the Romans who finally called him in and took him to task for the troubles that he was making.
