The reason why these areas are investigated is to demonstrate the lack of democracy present within our current system. A democratic system would bring the key issues to the forefront, debate them, inform the public and ultimately let the public decide what course of action should be taken. Instead, the key issues are ignored. Mostly irrelevant issues are hyped. The people are left ignorant to what is really happening and the power of the few remains unchallenged.
