9/11 Victim Wants Death Penalty For Alleged Terrorists, If Accused Want To Live

A man who lost his father in the September 11 terrorist attacks is all in favor of capital punishment for alleged mastermind Khalid Sheikh Mohammed … unless KSM wants to be a martyr.

Brett Eagleson — the president of 9/11 Justice, an organization representing 9/11 survivors and relatives of victims — tells TMZ … he wants to see the Al Qaeda terrorist rot in prison if KSM’s hoping to die for the cause — but he wants KSM dead if the guy is hoping for a cushy life behind bars.

Remember … KSM appeared headed for a life sentence as part of a plea deal with the U.S. government … but the Department of Defense yanked the deal off the table at the eleventh hour.

The pre-trial agreement required KSM to plead guilty to conspiracy charges pertaining to the 2001 attacks … and removed the possibility of a lengthy death penalty trial.

But, with U.S. Defense Secretary Lloyd Austin axing the deal, the death penalty is back on the table, as well as a trial … and that’s a win as far as Brett is concerned.

Still, Brett says the families of 9/11 victims were once again kept in the dark … as was the case when the plea deal blindsided Brett and the folks he reps.

Brett’s been demanding more transparency from the feds.

KSM and two of his alleged accomplices — Walid Muhammad Salih Mubarak bin Attash and Mustafa Ahmed Adam al-Hawsawi — appear headed for trial after all.
