Final answer:
CALEA was not passed to curb terrorism, whereas FISA, AEDPA, and the USA PATRIOT Act were enacted in response to terrorism concerns with the Patriot Act significantly expanding government surveillance capabilities.
Step-by-step explanation:
The legislation that was NOT passed in an effort to curb terrorism is CALEA (the Communications Assistance for Law Enforcement Act). CALEA was enacted in 1994 with the goal of enabling law enforcement agencies to conduct electronic surveillance more effectively, but it was not specifically aimed at counter-terrorism efforts.
On the other hand, FISA (the Foreign Intelligence Surveillance Act), AEDPA (the Antiterrorism and Effective Death Penalty Act), and The USA PATRIOT Act were all enacted in response to concerns about terrorism, with the Patriot Act being the most prominent among them, significantly expanding the government's surveillance capabilities post-9/11 to detect and prevent terrorism-related activities.
