Although law enforcement agencies represent the first line of defense against terrorism, the problem is so critical that other segments of society should also have an input. Terrorism has had significant impacts on physical security measures and surveillance procedures, which have in turn posed potential threats to traditional freedoms. Jurists have also examined the issue of international terrorism, particularly in the decision in Hanoch Tel-Oren v. Libyan Arab Republic. The revised Domestic Security and Terrorism Guidelines issued by the Department of Justice have clarified the scope of domestic security and terrorism investigations by the FBI. They will protect lawful political dissent while giving greater protection to the public. The Department of Justice also supports S. 2255 if certain modifications are made. This law would close gaps in existing law and give the President needed additional power to deal with international terrorism.
