New York City could become a possible target for terrorist attacks during the trial of terror suspects in civilian court, former Attorney General Michael Mukasey warned Friday.

Mukasey, the attorney general for the tail end of President George W. Bush's administration, slammed the Obama administration's decision to move alleged 9/11 mastermind Khalid Shaikh Mohammed and other terror suspects to Manhattan for trial in civilian court.

A former federal judge in New York who heard the case of American terror suspect Jose Padilla, Mukasey condemned the decision during a speech before the conservative Federalist Society's convention in Washington, D.C.

The conservative group dispatched updates from Mukasey's speech on Twitter:

Mukasey: Trying KSM and other Gitmo detainees in US is "unwise"

Mukasey: Obama administration is returning to a "September 10th" attitude, treating terrorost acts as "conventional crimes" #tcot #teaparty

Mukasey: Trial will become a "cornucopia" for those still at large, a "circus" for those still in custody

Mukasey: NYC will become the focus of the world and a possible target during KSM's trial

Mukasey: "I can't see anything good coming out of this." should be tried at GITMO

Mukasey: "There's a certain hydraulic pressure that tends to distort cases like this.'
