The Department of Justice has just sent a letter to the Senate Judiciary Committee answering early questions about how many terrorists have been convicted or plead guilty in civilian courts. Between those convicted of terrorism-related crimes (150) and individuals with ties to international terrorism convicted of other crimes (like obstruction or perjury–the total here is 240), 390 people have been sent to prison using our civilian courts. Not on this list? Right-wing American terrorists like Scott Roeder.
