is scraping of POTA responsible for terror attacks?

i think more than the legislation, its commitment of the adminstrators and security personals, rulers (politicians) and at last but not the least, the juducuary, which is more important. i think adminstrators and security personnels in our country are ignorant and incapable, politicians are insensible and on top of all, we all are corrupt. only then the role of judiciary comes where a legislation comes to play a role. If police and intelligence people want, they can arrest any one on petty grounds. even by existing rules.
