Counter-terrorist statutory authority is derived, in part, from which of the following acts?

The Anti-Terrorism and Effective Death Penalty Act is a key piece of legislation that provides counter-terrorist statutory authority. Enacted in 1996, this act was designed to strengthen the legal framework for combating terrorism in the United States. It not only increased penalties for various forms of terrorism but also provided federal authorities with enhanced capabilities to investigate and prosecute terrorist activities.

The act also established new crimes related to terrorism and expanded existing laws to include acts committed by domestic terrorists. It reflects a comprehensive approach to addressing the threats posed by terrorism, both foreign and domestic. As such, it lays the groundwork for many of the counter-terrorism measures and initiatives currently in place.

Other options do not pertain to the specific legal frameworks that directly empower counter-terrorism efforts in the same manner. Each of those acts addresses various aspects of national security but lacks the direct focus or legislative intent aimed at enhancing anti-terrorism efforts as seen in the Anti-Terrorism and Effective Death Penalty Act.
