CALGARY -- Kevin J. Johnston, who is running to become the next mayor of Calgary defended controversial and threatening comments he made on a weekend podcast, now has public officials ranging from the mayor to the police chief expressing concern about his prospective candidacy. Johnston said he was sick and tired of public health restrictions that have forced many Albertans to close their businesses. “AHS has done a lot of harm to a lot of people,” said Johnston on his podcast, The Kevin J. Johnston Show on Saturday. “I intend to do a lot of harm to AHS and I mean a lot of harm. God, you guys are not going to like what I do.”
