Absolutely nothing, this is how much of identity theft is done, do a little research and you can assume anyone’s ID at least for a time.
I recently had to show residency in my county to sign up at the Rec Center so I could use the gym.
They had me bring in a utility bill, but made no effort to determine whether the Sherman Logan referenced on the bill was actually me. I could have used a friend’s, or even one I rescued from somebody’s trash.
So what was the point?
