Condition of our politics

As we all remember the time of election of the president of India ... A case was filed there on pranks mukharjee which said that he cheated the people by his fake signatures and was undergoing the charge but was still made the president of the nation...
This example I gave was because it became a very popular case at that time and it is easy for us to link to it ...
But the question arrises that as to why was such a decision taken the question isn't to be stressed upon our honorable president but still the question stands before us that if we know that a case of lieing is pending against a nominee who is supposed to be the next fave of the country was chosen without looking into the matter as to what actually was the reality....
Are we so week and hollow that we don't even cross check and examine our officials... ?
Are we so greedy that we can't ever think about the country as a whole and our image in the world ?
Is there nothing that can actually help us improve upon these acts of stupidity being going on since years .. ?
There are many cases of big politicians and businesses men involved in this process of cheating and keeping the law in the dark but why are we so helpless and blind that we can't even raise our voice for our rights ?
