This was a JOKE from Day 1. A WALL, or at least a fence, will slow people down>>>>>>
A real wall or fence has to be patrolled and enforced. We don’t even do enough of that

You are right and I thought about it before. A wall will (generally) be an obstruction - but a bunch of sensors can simply be turned off, based on policy, and it’s as though they never existed.
With a wall - if it is breached, some decently placed cameras can REALLY have an impact. With sensors - forget it.
