The F.B.I. began recording numerous conversations in which Osmakac discussed his plans to commit a several violent terrorist attacks in the Tampa area. Osmakac also made attempts to obtain guns from various individuals. Osmakac was charged in a two count indictment with committing one count of knowingly attempting to use weapons of mass destruction, specifically explosives grenades and similar devices in violation of 18 USC 2332 and with possessing a firearm not register to him ,specifically a AK-47 machine gun in violation of 26 USC 5861(d).
Prior to trial, the government informed Osmakac it planned to offer evidence of information obtained from electronic surveillance conducted pursuant to the Foreign Intelligence Surveillance Act (FISA) during the time that Osmakac was being observed. Osmakac filed a motion asking the trial court to order the government to disclose certain FISA materials including the underlying search warrant applications and orders issued by the FISA Court. The district court reviewed the requested materials, in camera and ex parte, and determined that there was no valid or legal reason for disclosing any of the FIA materials. Osmakac challenged the district court’s decision denying him access to the FISA applications and supporting documents and the FISA Court’s order authorizing the surveillance of Osmakac, who was a U.S. citizen. Osmakac argued that he wanted to review the applications and orders to determine whether the surveillance and searches were in fact legal.
