A major sticking point in this week's pre-trial hearings for Khalid Sheikh Mohammed and four other men accused of plotting the September 11 terror attacks has been how the military commission will handle classified evidence.

Defense attorney James Connell says other motions can’t forward until that decision is made.

“It’s just another example of how many things around this process are unsettled,” he said, “how many procedures where we don’t know what the procedure is.”

Judge Pohl cancelled Wednesday's scheduled hearing after defense lawyers asked for time to submit additional facts to support their motions.

The delay leaves 9/11 victims’ family members, who came to watch the hearings, in limbo.

Matthew Sellitto lost his son, also Matthew, in the attack.  He and his wife travelled from Florida to Guantanamo Bay, Cuba, because he says they want to see the justice system work for their son. But that system can work slowly. Still, Silletto says the delay is proof the system works.

“Even low-lifes, excuse me, but low-lifes such as these people that made the plan that killed my son can have their day in court and even can stop the whole process,” he said.

Lawyers will meet with Judge Pohl to decide what if anything can be accomplished this week. Legal experts do not expect the actual trial to begin before some time next year. 

But even if the remaining motions aren’t acted upon this week, Silletto says he doesn't regret making the trip to Cuba.
