Daniel Pearl's Father is Upset at Obama's decision.....

This upcoming trial is going to be a circus...

The father of slain Wall Street Journal reporter Daniel Pearl slammed the Obama administration's decision to hold a public trial for admitted 9/11 mastermind Khalid Sheik Mohammed -- who boasted of killing his son in Pakistan.

Judea Pearl said he was "sick to the stomach" when he heard that the Justice Department decided to prosecute Mohammed in Manhattan federal court.

"I don't want to hear every morning in the papers what KSM did," Pearl told The Post last night. "Danny was killed once. Now he will be killed 10 times a day. Leave him alone."

His son's beheading in 2002 was caught on a gruesome video that shocked the world.

"The 21st century saw three shocks," Pearl said. "The first was 9/11. The second was the killing of my son. And the third was the shock today."

The reporter's outraged father, a UCLA professor, said a public trial would allow the admitted mass murderer to "boast about his cruelty" and encourage other terrorists to inflict harm.

Pearl said the prosecution of Mohammed should be done in closed session to avoid giving terrorists a platform.
