Sunny - Mere possession of AK56 is terrorism because it is a weapon of causing mass casualties and not self defense or even commit a regular sort of murder. The Shiv Sena leader as I understand was carrying pistols - which is OK to carry when there is situation of riots for pure self defence. There is a different thought process in acquiring an AK56 - and that is to kill a LOT of people - and we will never know what was going on in Sanju's mind then. Its not a good idea to release Sanjay Dutt. Not a big deal though about some leader carrying pistols.
