Politicans/glass houses/stones

Politicians trade on the public's short memory.This comes in useful with the tax avoidance evasion furore as they can present themselves as the people who are going to solve the problem and crack down on the guilty when it was only a few years ago the whole political class was in the dock for fiddling their expenses and the system was exposed as rotten to the core.Now it has been ostensibly reformed and their opportunity for malfeasance has been curbed they now want to present themselves as on the side of financial probity,going after the avoiders and evaders.If there was a Nobel prize for chutzpah they would all be sure fire contenders.
