Indian police system including CBI is not strong enough that we can secure release of terrorists who are hiding in Bangladesh or Pakistan. What we can definitely do is that we must nab local support sysyem and police if convinced and have solid proof of their involvment in terrorism activity like bomb blast just kill them in encounters.No need to go before courts where our lawyers and politicians will work to secure their release and even if vonvicted even by Supreme court will not hang them.
