it is changed or amended. amendments require when and as necessary. even in sea & air port too. now most of the airlines does not allow or encourage to carry liquid substances in flight after liquid bomb threat. law enforcement authorities are their to protect us by amending existing / old laws. v need to understand the situation & work accordingly.some times v ask the authorities to amend the existing law, when v fall in trouble.if u read daily news papers or the ministry sites, u would have saved ur time going there.
cheers guys & b happy
