“Yee discussed helping the agent get weapons worth $500,000 to $2.5 million, including shoulder fired automatic weapons and missiles, and took him through the entire process of acquiring them from a Muslim separatist group in the Philippines to bringing them to the United States, according to the affidavit by FBI Special Agent Emmanuel V. Pascua.”
