The Royal Canadian Mounted Police ( RCMP) on Wednesday has a new chief who, instead of setting his priority on fighting crimes, pledges to tackle scandals. Robert Paulson, who began his career with as a beat constable 25 years ago, is promoted on Wednesday to lead the 15,500-strong national police force charged mainly with tackling major crimes, enforcing smuggling and trafficking laws, investigating drugs, securities crimes, tax evasion and illegal immigration. The RCMP also conducts routine civilian policing in Canada\'s western provinces, the Atlantic coast provinces, and in the Arctic. Paulson, 52, said Wednesday that he is proud and privileged to have been promoted from the second-ranking position to the top job of RCMP commissioner. \"Mr. Paulson was chosen following a rigorous and open selection process. As a senior police leader with broad experience across the RCMP\'s complex mandate, he brings with him a deep understanding of the challenges facing the Force,\" Prime Minister Stephen Harper said Wednesday, adding \"Mr. Paulson will provide the leadership necessary to strengthen our national police force now and into the future.\" Paulson\'s appointment took place after months of internal struggle at the highest levels of the RCMP, along with new allegations by rank-and-file officers of sexual harassment and bullying. \"I recognize that I have a lot of work to do, a lot of work ahead as we continue to transform the RCMP,\" Paulson told reporters on Parliament Hill right after the announcement of his appointment. \"Accountability and leadership will be areas of focus for me and my team as we go forward,\" he added.
