POTA had nothing to do with terror control measures.
POTA was a weapon to mobile votes on hindutva lines. POTA was a weapon to settle ploitical scores. POTA does not have anything extra that already exists in our existing anti-terro laws, except that you can arrests someone without a case for a minimum of 1 year. A grave human-rights issue. POTA is epitome of a ploitical revenge and not a weapon to have a fool proof anti-terror law. US has PATROIT act (like POTA) in force even today. But much safe they today. How many from 9/11 have been convicted, charged and executed??? Think over it.
