DSST Criminal Justice Practice Exam 2026 – The All-in-One Guide for Exam Success!

The question tests which federal agency oversees the Federal Air Marshals. The Federal Air Marshal Service is housed within the Transportation Security Administration, which is part of the Department of Homeland Security. This placement fits TSA’s mission to secure transportation systems, including deploying undercover air marshals on flights to deter hijackings and enhance in-flight security. The other agencies have different primary roles—FBI focuses on investigations and domestic security, CIA on foreign intelligence, and NSA on signals intelligence—so they are not the parent agency for the air marshal program.
