The man who shot video of two masked gunmen — brothers Cherif and Said Kouachi — murder a Paris police officer on a sidewalk, later identified as 42-year-old Ahmed Merabet, now regrets sharing the footage online, saying he never expected it to be broadcast so widely. Engineer Jordi Mir told The Associated Press Sunday he posted the video out of fear and a "stupid reflex" fostered by years on social media. "I was completely panicked," he said. Mir said he left the video on Facebook for about 15 minutes before taking it down. It was too late. The footage had already been shared across the site and someone uploaded it to YouTube.
