A nationwide license plate recognition system tasked with reducing crime is being ousted from communities across the country — forcing local officials to reckon with mounting fears of federal surveillance during President Donald Trump’s second term.

Public safety company Flock Safety has billed its surveillance systems as a program to root out criminal activity on local streets, with its cameras already installed in more than 6,000 municipalities nationally. But as Trump’s deportation campaign brought an increased, forceful presence of federal agents to states across the country, some local officials in predominantly liberal cities and towns now argue the cameras themselves pose the bigger danger for their cities, offering federal law enforcement a back door for tracking residents’ movements.
