If these existed, would people continue attempt to cross illegally? The thought-provoking argument is that these pieces of technology, if foolproof, would go completely unused as people inherently value their lives (but not laws.)

140 documented victims of the clearly demarked killing zones of the Berlin Wall suggests they probably wouldn't go unused. Also can't imagine such technology being successful at actually stopping migrant flows somewhere like the US border unless the government moved to line the coast with them...
