Why bother installing a safety fence?

What the hell are the installers thinking? :roll:
An adult could have gotten under there, let alone a child.
I see this on about two thirds of my pool inspections, although most aren’t this bad

About the money and nothing else.

They won’t have any money if a child drowns and the parents sue.

Unless the homeowner installed it themselves. Those fence sections are avilable at Home Depot. I can’t imagine a contractor putting in something illegal like that.
