Concerns over how the government deploys facial recognition tools were on full display during a U.S. House of Representatives hearing examining the Department of Homeland Security’s use of biometric technologies held Wednesday morning.

The Committee on Homeland Security hearing lasted a little over two hours and broached topics related to privacy, data security, and even discrimination against women and people of color that could result from limitations inherent in facial recognition technology. By the time the proceedings drew to a close, it seemed unlikely that many of those concerns were inching any closer to a resolution.
