There are drug smugglers in punjab that get drugs from pakistan. This doesnot mean that north Indians are traitors or smugglers.
There may be some arms dealers in south India. These must be caught by police because they are selling arms. Today they are selling arms to LTTE tommarroy they can sell to Maoists or Islamic terrorists.
The majority of South Indian population is PATRIOTIC like any other part of India and we should just kick out the criminals and smugglers.
