Politics is dirty man and it's possible that whoever wears white, is also the man that's wearing red behind the curtain. So, if someone wants to show how clean they are, they need public records about it. And the people will have the verdict if the official is clean or not. But if their family as a history of plunder and other stealing cases from public funds, that's already telling one thing about his leadership. It's possible that who conducts the investigation is also behind the maneuver of the corruption so that they can divert the path onto themselves.
The world we lived in today is a cruel one and none of us would be held responsible for the social vices going on and on. Sometimes I ask my self, when will this end? I guess we would never know because human beings have completely a whole different settings of life and expectations.
Politics has to with bloodshed, terror and rigging. It consists of all kind of crimes and these politicians been held accountable for most of the crimes committed but at the end of the day, they walk freely like nothing happen. This doesn't only apply in Philippine but also in European and African countries.
