Charlie Hebdo’s chief editor, who goes by the name of Charb and has been under police protection for a year, defended the cartoons.

“Muhammad isn’t sacred to me,” he said in an interview at the weekly’s offices on the northeast edge of Paris. “I don’t blame Muslims for not laughing at our drawings. I live under French law; I don’t live under Quranic law.”

Charb said he had no regrets and felt no responsibility for any violence.

“I’m not the one going into the streets with stones and Kalashnikovs,” he said. “We’ve had 1,000 issues and only three problems, all after front pages about radical Islam.”
