Places along the indian coaastal lines of Karnataka and Kerala are known for arms smuggling. There are lots of places in Malabar (eg malappuram) where ISI has a very strong hold. Lot of Pakistanis live there and that place is predominantly dominated by Muslims. Ofcourse congress / cpi the rotating so called rulers of Kerala will never touch the area because of the vote bank and hence a safe heaven for Terrorists and ISI agents.
Well every one knows these things but no actions are being taken , Hyderabad blasts are just the beginning....
