I'm not sure we need much of a wall in the first place. Just cut the free shit. Give a deadline. 2 years and the teat dries up. Stay or go, your choice, but no taxpayer-funded handouts or healthcare, and no American Constitutional rights. You're not an American citizen. Make no mistake, some will ignore the warning and it will go poorly. Far less than the profiling and human round-up that it would take if you leave the incentive to stay in place. Anyone thinking I'm an ogre for putting it that way needs to spend time in STX to gain some perspective. The current system is a crap deal on all sides.
