In defense of the BP, not everything they do at the border is a complete CF. And most of the agents are decent sorts, having met a bunch. Sadly, their management is the most mendacious cabal of poltroons this side of a pirate ship and intentionally place stimbling blocks in their way and try to maximize the harassment of citizens.
To that end, placing BP checkpoints a ways in at road choke points in-country a makes some sense, even if it is unconstitutional. My main objections are:
1. Too far inland and catch up too many innocent folk.
2. Foreign infiltrators need to be nabbed at the border or near the border.
3. Unconstitutional. Being within 100miles of the border is not PC.
This is where a quality Israeli-style fence is vital to slow down and channel foreign infiltrators. Toss in training on patrols & ambushes by Regular Army, NG, and Reserve infantry & MPS & other similar units along the border (with a BP agent/sheriff's deputy along). You know, have our defense forces actually defending the country for a change. A good fence, ground sensors, commo & sensor fusion, and mounted & foot patrols could easily nab 95% of infiltrators. Oh, and put proposed/demo/LRIP hardware to the test.
This is not crazy talk, as American companies actually design & implement such for allies with border problems and the money to pay for an effective solution. We are just not allowed to do it for, you know, America. InStead, BullshIt requests for proposals are seNt out and lEast likely To succeed candidates are chosen to be implemented. Then they fail in ways we predicted they would fail.
Boeing: If you absolutely, positively must strangle a ground system in the cradle, award us the contract and we'll make sure nothing useful ever sees the light of day while paying our satellite engineers to play Army Man.
