Not every theft is equal.
Someone stealing food to feed their family may be committing a crime, but they’re doing so for a reason that many can relate. A person stealing simply because they want to own something they can’t afford or who steals for financial gain, has ostensibly committed a worse crime.
Add in that, in many cases, especially with self-checkout, it’s actually hard to know when someone has intentionally stolen an item or simply forgot to scan it. Most people have walked out of a store having never scanned that case of water or big pack of paper towels under their cart.
