Someone who forgot their dog food was on the bottom of the cart and leaves isn't committing theft, as long as they go back and make it right.

And worst yet, how do you tell a 17year364days old's image on pornhub and 18year old's picture? You get arrested for CP on the 17.364 image if you're caught and they know it's bad. Did it matter if the minor perjured themselves? Nope. Did they use a fake ID? Who cares. You're at fault.
Strict liability is absolutely in place in many states.
