You are accusing the Gospel writers of manipulating the truth because YOU CAN'T HANDLE THE TRUTH. The truth is that Pilate agreed to the demands of the Jews RELUCTANTLY, since Christ was PERFECTLY INNOCENT under Roman law.
It is amazing how people prefer the mythical over the real. The Gospels are true historical accounts which have greater veracity than any other historical records (apart from the fact that they have spiritual content).
And Peter -- A DEDICATED JEW -- accused the Jews of the killing of Christ (Acts 2:14,23; 3:12-15): But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words:... Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:... And when Peter saw it, he answered unto the people, Ye men of Israel, why marvel ye at this? or why look ye so earnestly on us, as though by our own power or holiness we had made this man to walk? The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Son Jesus; whom ye delivered up, and denied him in the presence of Pilate, when he was determined to let him go. But ye denied the Holy One and the Just, and desired a murderer to be granted unto you; And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses.
