The Movement for Black Lives (M4BL) spent tens of thousands of dollars on the masks they had planned to send all over the country. The first four boxes, each containing 500 masks, were mailed from Oakland, California, and were destined for Washington, St. Louis, New York City and Minneapolis, where on May 25 a white police officer killed George Floyd, a 46-year-old handcuffed Black man, setting off a wave of protests across the country.

But the items never left the state. The U.S. Postal Service tracking numbers for the packages indicate they were “Seized by Law Enforcement” and urge the mailer to “contact the U.S. Postal Inspection Service for further information.”…

It’s not entirely clear what law enforcement entity seized the masks or why. But the Justice Department, led by Attorney General William Barr, has taken an aggressive posture against demonstrations and on Thursday expressed concern about “extremist agitators” who are “hijacking the protests to pursue their own separate and violent agenda.”
