“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.
Right you are!
The Israelis have the best idea
In urban areas they need a wall and build one
But in remote areas their border fence is a heavy duty see through fence. Lots of well placed razor wire/ They have sensors and cameras
There is a patrol road running parallel to the fence and the Israelis respond to intrusions
