A group of steampunk cosplayers arranged to meet up at Westfield Plaza Camino Real near San Diego to ride the mall's Victorian carousel. But Westfield's mall cops were terrified of the cosplayers and evicted them all, escorting them to the door, calling the cops, and making them wait until the police arrived (the police basically shrugged and said, "Look, it's stupid, but it's their mall").
The mall cops -- and their corporate overlords -- cited a variety of dumb policies in support of the action, including a ban on wearing costumes that obscured the wearer's face (which didn't describe the cosplayers' outfits), a ban on gathering in groups larger than three (ORLY), a ban on photography without the subjects' permission (the steampunks, having gathered to have their photos taken, can be presumed to have consented to the pictures). Basically, it's a case of mall cop authoritarianism followed by the usual bland corporate doubling-down.
Of course, kids -- especially kids who happen to be brown -- already know that malls are capricious and fraught replacements for the public square. Mall cops basically hate anything that doesn't accord with their view of what a shopper should be and relentlessly discriminate against anyone they don't like.
