Shit if they're stealing a TV from major corporate retailer that has pushed out all the local competition: I didn't see that shit, either.
Oh and people who need baby formula from Walmart: The locks used on those cabinets use a universal key. Obtain one and even if they lock up the baby formula, you can still get it. Even if you intend to pay, it's a time saver if your Walmart is like mine and nobody ever shows up to assist you at the locked cabinets.
You think you're hurting the corporation, but you're hurting its employees. If a location becomes unprofitable because of too much theft, it just closes, and now all those people are out of a job because of entitled thieves' greed.
Also, the formula is locked up because people steal it to turn a profit fencing it, not to feed anyone who needs it out of the goodness of their heart.
But it is the thieves fault when shrinkage causes them to have no job at all. Prioritizing your selfish, greedy desire to steal over their well-being is all you're doing, and it's reprehensible.
