Domestic terrorism experts have been calling for better screening to help identify extremists before they’re hired. Some states, such as California and Minnesota, have tried to pass new screening laws, only to be prevented by police unions, whose legal challenges argued successfully that such queries violate free speech rights.
Without screening, white supremacists who get inside can operate with impunity, targeting Black and other people of color, and recruiting others who share their views.
“Unless your name ends up in an FBI wiretap” an officer will go undetected, said Fred Burton, a former special agent with the U.S. Diplomatic Security Service. “There are loopholes in the background investigative process.”
