The root lies in attitude of Bihari & UP people...Der's no point in blaming the leaders .. after al leaders like Lalu are a by-product of common thinkin prevalent der... if situation has to change first change ur attitude.. jus evading ur state n flocking to oder places wont do any good..do some development in ur states n work hard !! Today wot has happened in mumbai & maharashtra can easily in oder developed parts of india as well if it goes same way... u cant burden oders because of ur short-comings !!!! n as of rioting in bombay i think even dat is not justified.. its not d solution !!! it has oly caused trouble to common man..
