This immunity crap is crazy, it's counterproductive to the efforts of taking down those in the nation whom are pumping corruption throughout it, in that it makes the job of the men and women who's lives are put on the line to go out and interrogate these folks job much harder than it needs to be and the risk to their lives much greater.
If you are going to create an organization like the EFCC, then you need to do so with the intent on giving it some extra clout beyond that of the regular military or police force, the same should possibly be done for SSS as well, or else you'll start to see many more incidents like that in which took place in Plateau State as the intensity of this new-found witch Hunt picks up more and more speed.
Not all of the accused are going to be nice like Alam and go down without a fight. Most will go down like
THIS, and use their immunity to get away with it as long as they can. In the meantime more and more young bright eyed men and women, enthusiastic to do right, and defend the integrity of their nation... are sent to their early graves via the actions of these selfish fools, who don't even deserve to be free, not to mention in government and gifted with immunity from having to get in the ring with Lioness, Lady Justice.
