I think some people are forgetting that the moment, an anti corruption force is institutionalized, there's no guarantee that there wont be corruption WITHIN the group. (extremely oversimplified example) A congress member could just hire a team of angry college students to join an anti corruption and blow the whistles at the bjp, say.
I have a mathematical publication on corruption, if anyone wants it.
" Now therefore kill every male among the little ones, and kill every woman who has known man by lying with him.
But all the girls, who have not known man by lying with him, keep alive for yourselves. "- Book Of Numbers 31:17-18
