It's like a shoplifting conviction.
you can absolutely be charged with shoplifting before leaving the store, as the crime is often complete the moment you take possession of an item with the intent to steal it
And what is needed to show intent?
When the Crime is Complete (Inside the Store)
Concealing Merchandise: Hiding items in a purse, pocket, or under clothes shows intent to deprive the owner.
Altering Price Tags: Switching tags or removing security devices.
Passing Checkout: Walking through security gates without paying after concealing items.
Hur could not prove intent. Which is the hill you chose to die on.
