The shattered glass, bits of metal and discarded groceries strewed across Rue Beaurepaire have been swept up. The smoke from fires and tear gas is a memory. Wooden boards have replaced smashed windows.

It took Anita Lollchand, 68, five days to muster the courage to leave her apartment in search of groceries after the street, where she has lived for 40 years, devolved into a lawless zone of break-ins, looting, burglary and arson. In her building, young masked men burst into the foyer, ripped out the intercom and hammered at the glass on a second door. The glass cracked but didn’t give, and she trembles at the thought of what might have happened had they gotten through.

“We’ve seen so many protests here,” she said, breaking into tears. “This wasn’t a protest. It was a revolt.”

Oct. 17 marked a dark day in France. Large, peaceful demonstrations across the country were overtaken by riots, attacks on government buildings and looting. While admitting failures of security and intelligence, the government blamed both far-left insurgents and opportunistic delinquents.

The French Chamber of Commerce and Industry released its grim accounting this week. About 2,500 businesses across France were affected, and 47 percent of them were severely damaged. Some 480 were in the Paris region.
