"our parliament" is full of corrupt and useless politicians - they are not and have never been proved to be trusted with power. i dont support the role of agencies but i certainly dont like to see power concentrated in the hands of politicans - some who only ever get in because they are powerful and feudal.
Our society is full of corrupts...that includes you me, and system of govt evolves overtime & not overnight. If institutions are not allowed to work how can you expect them perform?
