Since the United States Supreme Court overturned Roe v. Wade last month, America’s extensive surveillance state could soon be turned against those seeking abortions or providing abortion care.

Currently, nine states have almost entirely banned abortion, and more are expected to follow suit. Many Republican lawmakers in these states are discussing the possibility of preventing people from traveling across state lines to obtain an abortion. If such plans are enacted and withstand legal scrutiny, one of the key technologies that could be deployed to track people trying to cross state lines is automated license plate readers (ALPRs). They’re employed heavily by police forces across the US, but they’re also used by private actors.
