Former Prime Minister Jean Chretien's son has been convicted twice of rape. Both times the punishments were "smoothed over" and he got a tap on the wrist.
Most Canadians don't know it. The State owned TV network, who hates conservatives and loves liberals, didn't really mention it.
Could you give details from reputable sources? A search of Canadian media finds that Chretien's 33-year old adopted son was indicted on two charges concerning the same person in 2002 and acquitted by jury in Yellowknife of all charges in 2003 after 5 hours of deliberation. As far as I know, there hasn't been a prior conviction and there was no later election in which Chretien ran. Sorry, you might have to learn to check facts.
