Anthony Chambers, counsel to Nigerian terrrorist, Umar Farouk Abdulmutallab has termed the sentence given to the innocent-looking boy who attempted to blow up a U.S-bound plane on Christmas Day in 2009 as cruel and unconstitutional.

Abdulmutallab who pleaded guilty to a failed terrorist attack in October showed no signs of remorse but he rather called it a revenge mission against United States for their ill treatment of muslims.

His attorney has argued that the mandatory life sentence be appealed/reduced as the plot to blow up the plane eventually failed.

The notice of appeal was posted on Friday in the electronic court record for federal court in Detroit.
