The RCMP recently raided a journalists home supposedly in the name of “national security.” They tailed her for weeks beforehand. The assumed reason for the raid is that the journalist was investigating some irregularities in the deportation of a man named Maher Arar; specifically some involvement by the RCMP. The RCMP may have been looking for her sources to “plug the leak.”
