Minneapolis, MN – The trial of Mahamud Said Omar entered its second week here, Oct. 9, with the prosecution putting Joint Terrorism Task Force officer Martin Siebenaler on the stand. Siebenaler opened up a gun case and pulled out an AK-47 machine gun. Siebenaler then proceeded to say that the gun, which came from an ATF collection, was “most similar to” the weapons used by young resistance fighters in Somalia.
