Loitering is neither imaginary nor a "crime." However, loitering (meaning "standing around in a certain place for a prolonged amount of time with no purpose") is bad for business. People blame Amazon for the death of enclosed malls. However, strip malls are doing fine (just drive around Columbia to see what I mean). So what is killing enclosed malls? One major thing is large amounts of unruly youth who make it inconvenient or uncomfortable for actual paying customers.

Don't get me wrong, I hung out at malls when I was a teen. However, that was literally during a different millennium, back when mass shootings were rare. This is a different day and requires a different approach.
