Ohio has passed a law that lets police arrest people for videotaping movies in theaters. Governor Taft signed the bill last month and it takes effect in March. The film industry is trying to prevent piracy and they have several methods to fight it, including bag searches for people entering movie houses. But some say Hollywood's tactics could backfire. A recent study found that three out of every four movies leaked on the Internet came from industry insiders. That led the Motion Picture Academy of America to temporarily stop sending ``screener'' tapes and DVDs to Oscar voters.
