This is the result of Cong's historic intransigence and shenaigans for purely political expediency - for fear of upsetting their potential vote-banks, they've allowed the ULFAs and others to commit such heinous crimes with complete impunity. Even to this day, this do-nothing, useless Cong govt, run by incompetent, spineless, myopic idiots have no comprehensive policy for dealing with the myriad insurgencies afflicting this backward,balkanized, poverty-stricken land - in fact, it's precisely their communal-centric policies have served to further divide the country, and sow the seeds of such mayhem.
