How ‘bout rigging the whole area with landmines ? (I say straight-faced after spending the last 3 hours being audiologically raped to the point of vomiting by our ILLEGAL f*ckwit neighbors).
Tangle foot, razor wire, bouncing betty’s, any type of anti-personnel mines, i.e, claymores, etc..... I can think of lots of ways to have fun on the border, thanks to my military training.
Oh yeah, can't forget water boarding. That always works.
Dude-— if you know for certain they are illegal, then I would be reporting them on a daily basis to every authority I could get a phone number for. I would not stop until they were either gone, or I was arrested...
