if you read the original story, which is a masterpiece by itself btw and for that i would like to take this opportunity to congratulate with johncb for its awesome job done, you would know that the cops Are the corruptors, until the point where parker gets corrupted enough to take action on his own.
and i would like to add that for me, the cops are the real protagonists of the story, saw through the POW of parker. and i still see it this way in this kinetic novel
granted, this kinetic story is quite different so there is no way to know for sure where all this is going and in which way, but there are several pointers that can give you hints
on and english is not my main language, so pardon me the grammar, i know i do quite a few mistakes here and there
