AI and the “Airportization” of American Life

​We’re all resigned to the need to go through security at high-profile sporting and cultural events, just as we do at the airport. The American Civil Liberties Union is raising the question – will that level of scrutiny be the new normal at the mall, at open-air tourist attractions, outdoor concerts, and just plain walking around town?
 
The Department of Homeland Security (DHS) is investing in research and development to “assess soft targets and address security gaps” with new technology to track people in public places. It is funding SENTRY, the Soft Target Engineering to Neutralize the Threat Reality. SENTRY will combine artificial intelligence from the “integration of data from multiple sources,” which no doubt will include facial recognition scans of everyone in a given area to give them a “threat assessment.”
 
We do not dismiss DHS’s concern. The world has no lack of violent people and our country is full of soft targets. Just hark back to the deranged shooter in 2017 who turned the Route 91 Harvest music festival in Las Vegas into a shooting gallery. He killed 60 people and wounded more than 400. A similar act by a terrorist backed by a malevolent state could inflict even greater casualties.
 
But we agree with ACLU’s concern that such intense inspection of Americans going about their daily business could lead to the “airportization” of America, in which we are always in a high-security zone whenever we gather. ACLU writes that “security technology does not operate itself; people will be subject to the petty authority of some martinet guards who are constantly stopping them based on some AI-generated flag of suspicion.”
 
We would add another concern. Could SENTRY be misused, just as FISA Section 702 and other surveillance authorities have been misused? What is to keep the government from accessing SENTRY data for warrantless political surveillance, whether against protestors or disfavored groups targeted by biased FBI agents? If this technology is to be deployed, guardrails are needed.
 
PPSA seconds ACLU’s comment to the watchdog agency, the Privacy and Civil Liberties Oversight Board (PCLOB), that asks it to investigate AI-based programs as they develop. Congress should watch the results of PCLOB’s efforts and follow up with legal guardrails to prevent the misuse of SENTRY and similar technologies.
