To serve and defect.

It’s worth remembering that Charlottesville did everything it could to prevent the demonstrations, issuing permits only after being sued by the ACLU. And when push came to shove—literally—on Saturday, police and National Guardsmen were to be found only on the periphery of the brawling. Indeed, the Virginia ACLU reported that police were refusing to intervene unless specifically ordered to do so.^[1]

Shades of Berkley when cops similarly did not intervene to stop AntiFa violence.^[2]
