In the wake of the shooting tragedy in Newtown, Connecticut, Dick's Sporting Goods has announced that they will be suspending the sale certain semi-automatic weapons...like the one used in last Friday's Sandy Hook Elementary shooting.The store said in a statement Tuesday morning, "We continue to extend our deepest sympathies to those affected by this terrible tragedy." According to CNN, "The move comes after reports that investigators were trying to determine whether the gunman in the Newtown shooting, Adam Lanza, tried to buy a gun from a Dick's Sporting Goods store in the city of Danbury, about 12 miles away."Dick's has stated that "Reports that the suspect visited one of our stores last week have not been confirmed by law enforcement. Based on our records, we can confirm that no firearms were sold to the suspect identified in this case."Meanwhile, mega-retailer Wal-Mart said yesterday that it would continue to sell guns, including rifles like the one used at Newtown according to reports by Bloomberg.com.Bloomberg also reports that Wal-Mart has about 10 modern sporting rifles, the gun industryâ??s term for firearms that look like an M-16 military rifle, listed on its website. The retailer removed a description and picture of the Bushmaster AR-15, which was the model used in Newtown, after the shootings, but other rifles in the same category remained listed.Wal-mart does not sell guns directly from its site, but instead refers online shoppers to the store nearest to them.â??We remain dedicated to the safe and responsible sale of firearms in areas of the country where they are sold,â?? David Tovar, a spokesman for Wal-Mart, said yesterday.According to Bloomberg, online searches of five kinds of semi-automatic rifles on Wal- Martâ??s website showed them to be out of stock at stores in five states, including Pennsylvania, Kansas and Alabama, as buyers snatched them up for fear of further restrictions on such weapons in the wake of the Newtown tragedy.Meanwhile, magazines for handguns and modern sporting rifles are being "bid up" on auction sites like Ebay as users who fear additional curbs or outright bans buy up available inventory. Who do you side with? Dick's, or Wal-mart?
