“Calhoun County Sheriff Greg Pollan told FoxNews.com an argument quickly escalated into a fatal gunfight between Wayne Therman Harris and Chris McGonagill in Calhoun City, Miss. The shooting took place just outside McGonagill’s home, where he, Harris, and three other men were having a barbecue before things got heated between the two friends. Harris, who received a full pardon from Barbour for the sale of marijuana, was shot twice in the leg. McGonagill was shot seven times and died during surgery at Baptist Memorial Hospital in Oxford, around 12:30 a.m. Friday morning.” The fact that Mississippi’s gov pardoned the shooter isn’t as shocking as the revelation at the bottom of the story: “Officers are checking to see if the two men had licenses for the weapons involved, a .20 mm rifle and .9 mm pistol.” We’ve been reporting on criminals toting .9mms for a while, but the .20mm long gun is a new and worrying development. The two together? Small guns. Big story.
