At least 5,000 National Guard members and 2,000 troopers are fanning out statewide to bolster local police in advance of June 14 protests over federal policies.
The U.S. attorney in Los Angeles said a key arrest was made as authorities try to figure out who is funding and supporting the unrest that began on June 6.
They won’t arrest suspects but will detain them until local authorities arrive, the general said. Marines’ rifles will not be loaded with live ammo, he added.
