PORTLAND, Oregon (Reuters) - Federal prosecutors, citing national security concerns, urged a judge on Thursday not to force them to turn over to the defense more materials in the case of a Somali man charged with trying to blow up an Oregon Christmas tree-lighting ceremony.
"There are important national security concerns that militate for limited discovery in certain areas and which should guard against an unwarranted fishing expedition," court documents filed by government lawyers on Thursday said.
Mohamed Osman Mohamud was arrested on November 26 after he allegedly tried to detonate what he thought was a car bomb during a crowded tree-lighting ceremony in Portland on November 26.
The bomb was actually fake explosives provided by undercover agents.
Mohamud's attorneys have asked for more materials from the government as they prepare their defense, including recording equipment that allegedly failed during a crucial meeting between undercover agents and the alleged jihadist.
The failure to record the meeting was human error and "giving the defense access to the device would serve no proper purpose," prosecutors said in their court filing.
The government attorneys said they have already provided Mohamud's attorneys with a voluminous amount of materials including e-mails, audio recordings, video recordings, computer evidence, phone recordings, photographs and FBI reports.
