The city of Detroit is suing Black Lives Matter protesters after a group of organizers sued the local government.

Detroit’s suit alleges that demonstrators who participated in the racial justice protests this summer were a part of a “civil conspiracy” in which they attempted “to disturb the peace, engage in disorderly conduct, incite riots, destroy public property,” and resist police orders, among other “illegal acts.” The suit was filed in September, about a month after activists filed their own suit, alleging Detroit police officers “repeatedly responded with violence,” according to the Intercept.
