Walmart should be at least $500 million poorer because of the upcoming tort litigation.
I've never liked Walmart, but until the recent massacre in El Paso its inadequate security wasn't one of the reasons. Now it's the main one.
Around ten years ago, if not earlier, Walmart executives surely became aware that mass shootings had become an almost commonplace feature of life in America. And they surely had enough brains to know that a Walmart store would be an ideal venue for one. Security adequate to prevent such slaughter would have been at least three well-armed personnel at the smaller stores during business hours, and at least four at the bigger ones. Just common sense, but Walmart decided not to provide such security. It would have significantly increased costs and therefore hurt the retailer's profit picture.
In short, Walmart executives put their precious profits above employee and customer safety. For that their business deserves a big financial hit, and a team of good tort attorneys will probably be giving it one in the not-too-distant future.
