Did you think that up all by yourself?
Of course they would be used and then information gained acted on.
(Duh)
That's a nice looking infrared photo at the top of the page. You think anybody acted on that??
If they acted on the information they have, we wouldn't have the problem, now would we?

Right. Just like they act on the sensor and fixed camera information they get now.
The problem was never the technology. The problem was lack of will to act. We have ground-based sensor systems that keep, for example, an airtight cordon around the Gaza Strip, and are used in mission-critical force protection applications. We COULD have a border where only a statistically insignificant nunber of people could cross by sneaking around checkpoints overland. We DON'T because evil - yes I mean evil - people like Asa Hutchinson don't want us to have that.
