Who killed Jesus?
The Sadducees were a cult of priestly lineage which controlled the Temple service in that time. The Torah requires such lineage for service, so obviously the tribe demanded a great deal of power. Ultimately, they rebelled against the Jewish nation and were considered a heretical sect, often called minim in the Talmud. They rejected all court decisions and maintained their own courts, bound by none of the laws to which the Sanhedrin, the true ruling body, was bound. Thus the trial of Jesus could be held on Pesach night (in Mat, Mark, Luke) or Pesach Eve (John), both illegal for such judgment in a Jewish court, held in the house of the High Priest, also an illegal place as the sanhedrin met in the room of Hewn Stone, and they judged him to death for "blaspheme", based on statements that he would destroy the Temple and that he was the Messiah, neither of which is blaspheme in a Jewish court (but rejection of the principle of the coming of the messiah is a known Sadducee position). Obviously, the different versions of the stories have very different circumstances, but it is clear in all that the Sadducees, "the chief priests and scribes" were the holding the court, and they had the alliance and sway with the Romans to get political cooperation for the execution.
These Sadducees were bitter enemies of the Jewish sages, the Jewish people, and dangerously heretical in their stances
So even if one were to hold that the entire New Testament were true and historically accurate as written, there is no reason to hold the Jews responsible for the killing of Jesus. Sorry Mr. Gibson, but you are wrong. Blaming "the Jews" is no more accurate than blaming "the Americans" for the terrorist acts of the Weather underground or the Klan. Certainly, in our times, we can finally accept the facts and even the most devoted fundamentalist Christians can rest easy in the fact that neither the Jews of today nor their ideological forebears and philosophical roots had anything to do with killing Jesus.
One of the underlying principles of Passover is that "in every generation, they have stood over us to destroy us" and this sad mistake has been part of that for the past two millenia in many parts of the world. Reach out and correct this grievous error, which is based on ignorance of history.
