If you're referring to the Jaffer case in Orangeville, the Crown Attorney has said the police botched the arrest and the conviction they got (dangerous driving, a Criminal Code offence rather than a Highway Traffic Act offence) was the best they could do under the circumstances. Jaffer is also no longer an M.P., having lost his seat in 2008. He is married to an M.P. whom the prime minister has expelled from caucus pending a resolution of an investigation of allegations of influence peddling by her ex-M.P. husband.
