TSA blacklist now based on hypothetical assessments

ACLU - Thanks to [a] GAO report, we now know that the TSA has modified the Secure Flight program so that it assigns passengers to one of three risk categories: high risk, low risk, or unknown risk. We've long been critical of this kind of passenger profiling—which the TSA has proposed in the past—because it inevitably leads to greater intrusion into individuals' private lives. And of course, it raises the question of what criteria and information the TSA uses to sort people into these categories.

The TSA is keeping those criteria secret, which is part of the problem. However, the GAO report states that the "high-risk" passengers aren't just those who appear to match a name on the FBI's No Fly, Selectee, or Expanded Selectee lists (as problematic as those lists may be). Now, the TSA is also using intelligence and law enforcement information, along with "risk-based targeting scenarios and assessments," to identify passengers who may be "unknown threats."

In other words, the FBI's flawed definition of someone who is a suspected threat to aviation security isn't relaxed enough for the TSA, so the TSA is creating its own blacklists of people who are hypothetical threats. Those people are also subjected to additional screening every time they fly. To make matters worse, another recently published GAO report indicates that the redress process for travelers who have been incorrectly caught up in the watchlisting system does not apply to these new TSA blacklists. So the TSA's "unknown threats" are truly without recourse.
