The BBC reports,

Gibson’s 2004 depiction of Jesus Christ’s crucifixion had been attacked by Jewish leaders, who said it could incite hatred towards Jews.
He told US TV’s Good Morning America he was “ashamed” of what he said.
“I was subjected to a pretty brutal public beating. I thought I’d dealt with that stuff,” he said.
“But the human heart can bear the scars of resentment, and it will come out when you are overwrought and you take a few drinks,” he told ABC interviewer Diane Sawyer.

Awww, the poor baby. He really is a victim, isn’t he? Cue violins and lame excuses.
In related news, I have no idea WTF Foxman is thinking, but at least Gibson had his priorities straight through the whole ordeal.
