Nevertheless, over the next few weeks National Guard troops broke up any assemblies of more than four people who congregated for any purpose on the streets of Berkeley, day or night. In the early summer, troops deployed in downtown Berkeley surrounded several thousand protesters and bystanders, emptying businesses, restaurants, and retail outlets of their owners and customers, and arresting them "en masse". At one point, the National Guard arrested 482 people by sectioning off a large part of a main street, including protestors and bystanders.
