Walmart doesn’t actually care much about theft. It’s a small percentage of their revenue, despite what they and the media want you to think. An industry lobbying group has recently said shrink is up to 2-3% last year, up from 0.7-1% pre-pandemic. Being a lobbying group, I’m sure those numbers are inflated to further their agenda. Do we really think that an extra 1% shrink is something Walmart is actually going to make massive changes over? No, they’d clearly rather install self checkouts that make it easier to steal so they can fire cashiers instead.
Those cameras are actually to monitor for Union activity.
It’s the DOJ that would determine whether to prosecute. Almost surely there is a policy of not arresting sitting members of Congress, there are valid reasons for this. But if Congress expels him like they should… free game for the DOJ there.
