Criminal defense lawyers representing a group of weapons dealers in a foreign bribery prosecution in Washington want a federal judge to throw out the case over allegations the government crafted and closely scripted a conspiracy just to prosecute it.

Attorneys in the Foreign Corrupt Practices Act (FCPA) case this month filed court papers urging Judge Richard Leon of Washington’s federal trial court to dismiss charges that stem from a government undercover sting set up around the sale of $15 million in military and law enforcement equipment to Gabon. Leon is set to hear the defense motions, which also include claims of entrapment, on April 4 in the U.S. District Court for the District of Columbia.
