When thinking about police useof facial recognition, most Americans probably fall somewhere between two extremes. On one side is the approach taken by San Francisco and Somerville, Massachusetts, both of which earlier this year banned municipal agencies, including the police, from using facial recognition. On the other is the view expressed by Michael McCaul, a Republican congressman from Texas, who during a hearing of the House Homeland Security Committee on July 10th announced: "When somebody is in the public domain...there's no expectation of privacy." Imagine a world in which cameras equipped with facial recognition were ubiquitous. In Mr McCaul's view, a permanent government record of everywhere everyone goes would be the price people pay for leaving their homes.
