From Fox News:
Wild video shows masked ruffians blatantly attacking a police cruiser while an officer was inside during a chaotic street takeover in Maryland.
Video and witness accounts show drivers swarming the intersection of East West Highway and Connecticut Avenue shortly after midnight Feb. 22 in Gaithersburg, Maryland, blocking traffic in all directions and performing high-speed “donuts” as onlookers stood in the roadway. Montgomery County police said it started around 12:39 a.m., when a large caravan of vehicles tied to takeover activity was spotted heading toward the Silver Spring central business district. Officers moved to monitor the group and closed several intersections to limit access and protect the public.
