It is shame to say that due to few people this are all things are happening, like in west bengal you can find most of bangladesi's, Why Wset bengal governament is allowing? for only Vote purpose. If they would have been implemented strict security rules on border areas. this kind of things would not be happend. The governament is not implementing stict rules, every where corruption. Specially in border areas if some one gives 50 and 100 rupees then BSF people allow them to india.
