Protesters in Brooklyn Center, Minnesota, began placing embattlements on the streets outside the police headquarters building as the city’s curfew approached. They also carried improved shielding to allow protesters to hide from police projectiles while they throw objects at the police.
Washington Examiner reporter Nic Rowan tweeted a video showing protesters erecting “embattlements” on the street to provide cover for protesters attacking police.
A video tweeted by Daily Caller journalist Richie McGinnis shows the defensive tactics in operation as police fire crowd-control munitions.
Protesters have upped their shield game big time.
