I like your first analogy. Your second analogy, on the other and, seems to me to justify the action. I think Macy's would thank you rather than call the police, but that's just my opinion.
Better analogy to what happened: Imagine you steal the $300 shoes with your new fangled trick and the mall security do not notice at all. You come back the next morning with the $300 shoes in-tow and then they call the police.
