Nonsense. It was the Jews who had Jesus arrested, and insisted on His execution for violating their religious laws against blasphemey.
The Romans had no interest in executing Jesus. They only did so under pressure from the Jews.
Pilot himself said he found no fault in Jesus to deserve death and washed his hands to symbolize that it was NOT his decision..but the Jews that Jesus die.
In fact the Jews responded to Pilot by saying "let His blood be on our heads".
The Jews are directly responsible for the execution of Jesus..and the Romans were just the channel of authority they needed to take in order to make it happen.
Mel Gibson is right.
