he is the main source for Indian Intelligence/Police to nab/keep track of dawood and other don's activities as abu might have established good network by now. Authorities must use him for these purposes and they must nab corrupt officials/politicians involved in all the crimes/offences committed with the help of underworld. As of now he is an important route to most wanted dons of india and as well as Pakistan's ISI activities. Some corrupt officials/politicians/stars might already have feared of abu disclosing their names. They might try to influence death penalty to him to save themselves.
It should not become like another Veerappan's Case as he died without disclosing officials/politicians associated with him.
