Final answer:
PACT refers to the USA PATRIOT Act, a law enhancing federal surveillance powers post-9/11, and a plea bargain is a legal agreement for a reduced sentence in exchange for a guilty plea.
Step-by-step explanation:
PACT stands for the USA PATRIOT Act, which is an acronym for Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act. This law was passed by Congress in response to the 9/11 attacks and significantly expanded the abilities of federal agencies to monitor electronic communications to enhance national security.
Additionally, the term plea bargain refers to an agreement between a defendant and a prosecutor, where the defendant pleads guilty to a charge or to less serious charges in exchange for a more lenient sentence than they might receive if convicted at trial.
