Not everyone has car, don't use hammer to kill a fly: SC on metro curbs before CJP protest. Expressing concerns over closure of 57 metro stations ahead of CJP's protest on October 10, the Supreme Court said that everything cannot be shut. "Everybody does not have a car," it stated. "Take measures only to the extent necessary to prevent certain things. But that does not mean you should use a hammer to kill a fly,".
