Let's be fair. This move has nothing to do with them trying to stop mass shootings or anything of the sort. It's not in any way an attempt to take action against violence. It's just a "sensitivity" thing: not openly talking about (or in this case, advertising) something that people are currently upset about or especially sensitive to due to recent tragic events. They're not going to stop selling the games, nor are they going to stop selling guns for the same reason. The displays they're removing aren't even specific to video games--just anything referencing violence. This also includes movies and hunting videos on display, as outlined in the employee handout. Walmart is not trying to stop shootings, so claiming that they're blaming video games for violence is a bit fallacious here.
