Down here in Texas Perry has put in a pretty neat system of infrared sensors on towers along the Rio Grande.
They detect and call the authorities. I take it they have it tweeked to know the difference between a deer and a Mexican. Any how, it has to be cheaper that a soldier every 100 yards along a 1250 mi border in 112 degree heat
I guess any asshole could shoot the sensors out but honestly, what are we to do? Who is going to pay for it all?
IMHO opinion it is best for the Feds and the Border states to Lean hard on Mexico.
None of this mordida BS
Then let the locals pick up the stragglers.
If these folks have no incentive to be here they wont come.
Mexico is one of the most horrific governments on the planet.
They are swimming in resources and the people are starving.
When I Talk to locals that get sympathetic to Mexico and want Uncle Sugar to fix it I redirect their attention.
