Rick Perry says fences work in urban areas but that a 1200 mile Texas-Mexico wall, and then a wall 800 more miles to San Diego will not work as advertized (terrain, length, not secure unless completely monitored). He wants drones for Intel and boots on the ground.
Beyond that, the Feds do nothing of consequence when they overstay if here legally, or picked up and found to be illegal -- the Feds really, actively assist them in avoiding return. A wall is just a bandaid. In truth it will solve nothing. Perry has studied using drones in Israel -- they use walls too (as Perry says do work in urban areas but Israel security relies on drones).
There are better ways to stop this flow of people. Including, as Perry has said, "a conservative ascendancy." Get rid of the draw -- the "social justice" programs without throwing Hispanics into the Democratic Party.
But Perry is not for amnesty and has said that the border MUST BE SEALED before anything else can come to the table. He's seen how the trick of allowing citizenship is followed by an unguarded border - time and time again. So he will not "play" that game again.
The only way to stop illegal immigration is to fence as much as u can, use the drones and have a sufficient number of law enforcement to take advantage of these measures. And to get rid of this corrupt government. If Homeland security and DOJ cannot figure it out then fire the lot of them, they are frigging useless.cannot
