The way I understand it they (Wal-Mart) are being pressured by that government agency that is totally out of control the ATf&E. ATF&E are pressuring others as well to do the same thing. If they can hurt business enough, or make it cost prohibitive the big stores will quite selling guns.
You old guys think back remember when Western Auto sold guns? Every hardware store had a gun counter. Then ATF started making it harder and some of the smaller sellers stoped selling guns. Then they started putting pressure on the small FFL dealers, the little gunsmiths shops and the small Mom And Pop places. Many of them quite selling because of the book keeping required. Then they went after the larger stores and larger gun shops. Sears and Penny's quite selling guns. Now that they have run most of the gun shops out of business, they are going after the bigger stores that still sell guns. Wal-Mart has quite selling guns in many of their stores because they were not selling enough to make a profit at those stores. Now they are requiring the Wal-Mart stores to keep video records, that will drive customers away. When the profit margin drops the store will drop the sell of guns. Then ATF&E will go after the sporting good dealers that have gun counters like Cabela's, Outdoor World, Sportsman's Warehouse, Gander Mtn, and all the others. Eventually they will run all gun sellers out of business. Then with no corporate customers the gun manufacturers will shut down. The way things are going in that arena there won't be many left to shut down any way. NEF was bought by Marlin, Marlin was bought by Remington. Now who is going to buy Remington, Ruger, Savage, T/C, Mossburg, or Weatherby?
