WACO, Texas  - A Muslim US soldier turned conscientious objector was jailed for life after being convicted of plotting to kill troops and their families from an army base. The court had heard that Naser Jason Abdo, 22, planned to attack soldiers and their families from Fort Hood, a sprawling army installation northwest of the Austin. Manacled and wearing a mesh cover over his face because he had spat blood on three officers earlier this year, Abdo made a long, rambling statement that ended in a vow to pursue “jihad” for the rest of his life.
