Well in case you haven't noticed we already have problems, big problems, and those problems are the direct result of the government not doing it's job.
So when the government refuses to do the job that they were hired to do then it becomes the reasonability of the people to correct that. And that's what these people are attempting to do. And quite frankly I would like to see more of it.
Believe me --I've noticed the problems and I live in an area where there are huge problems including an economic disaster where hospitals are on the verge of bankrupcy ---and not just from illegal immigration but out-of-control legal immigration including anchor babies handed easy citizenship and welfare benefits. However I can see many many problems with citizens taking these matters into their own hands.
