In recent days, the terms “Special Interests Aliens” (SIAs) and “Known and Suspected Terrorists” (KSTs) have become more frequently used as part of discussions about the federal budget and border security. These terms are not synonymous nor interchangeable, but are two separate terms that are commonly used in the national security community to describe different types of potential threats. These are generally well understood terms that are, unfortunately, being misunderstood or mischaracterized as part of the current shutdown debate.
