For me, I think it would depend on what time of life this occurred during. When I was younger, I was less strong in my convictions, and might not have brought the issue to light, or might have tried to do it via a soft approach. Nowadays, I'm less gentle, and, depending upon the circumstances, might just blow the whole thing wide open. Of course the right thing to do is call it to the attention of higher ups, but then again, there are some forces where the corruption starts at the top, and also, cities/areas where the corruption exists high above any one agency, with city/county/state officials, and flows downward. So, I think there are many factors to be considered. I saw an article recently stating that drug cartels have infiltrated all levels of law enforcement (in the U.S.), meaning local, state, and federal, which is a very scary thought, especially for one considering confronting corruption, when it's possible you could be approaching someone who's involved, and it could mean death to you and/or your family.
