More than 2,400 National Guard soldiers toting military assault rifles are on California streets. Authorities say that has allowed police officers to crack down on the rampant vandalism and thievery that scarred the first several days of demonstrations.

While the vast majority of protesters are peaceful, there have been violent clashes with police in Los Angeles, Sacramento, the San Francisco Bay Area and other cities. Police say the troops are not playing a traditional law enforcement role, but are guarding key areas.

Critics have asked for the troops to be recalled, saying additional law enforcement will only further violence against people of color.
