Funny how technology changes things. First you could count your things, and if something was missing, someone had stolen it. Simple.
Later, you could count other peoples things, and if they had something that was exactly what you had, then they had stolen it.
Now you look at peoples things, and if they have a map to where your stuff is, they have stolen it.
