Seems like folks with Bihari origin are more willing to entertain the RAW boogyman involvement.
Few others before you tried to use "boogyman" propaganda escape on RAW's defence but everytime RAW proven other before you and you wrong. We have seen how RAW concocted story of ISI money and its officials even asked Prothom ALO to publish its propaganda. We have seen how RAW trained and run killing squad making killing run on foreign diplomat, journalists and politicans and made them disappeared.
When you can not defend your stand start calling people "bihari", "rajakar" never proves your point nor make your labeling any true. Besides, when you and your type who label other people with "bihari" and "rajakar" will realize that 40 years after the independence there is no use of these Awami supressive tool? "rajakars" are long gone along with natural evolution.
