BOSTON (AP) -
Lawyers for Boston Marathon bombing suspect Dzhokhar Tsarnaev are again asking a federal judge to lift special restrictions that have been placed on him in prison, saying they are impeding their defense.
The lawyers said in a court filing Thursday that the FBI has been monitoring the case and that the Bureau of Prisons has tried to screen digital documents they have tried to view with Tsarnaev. They say that violates Tsarnaev's constitutional rights to have his case prepared without government interference.
The lawyers say the restrictions "threaten the integrity of attorney work product."
Prosecutors say the restrictions are necessary because of the suspect's "commitment to jihad" and "widespread notoriety."
Defense lawyers previously asked U.S. District Court Judge George O'Toole Jr. to ease the restrictions. Prosecutors lifted some.
