Well there is a problem with what you purpose. Keep the all the illegals in your home town along with your peace and quite, kids, dogs, etc.
Illegals don't stay in your home town do they, no they travel to and pollute the volunteers home towns costing a small fortune for their care, feeding, education, medical bills, housing, and services, including WIC, Medicare, Welfare.
It would be nice if the border patrol were allowed to do their jobs, but they are not doing the job. So it would seem that some American citizens feel the need to take it upon themselves to stop this invasion that the congress is charged with protecting us from, according to the Constitution, a obligation they have chosen to turn their backs on.
I would think that a wait and see if citizens can get the job done in a sane manner before getting in a twist about it. Not trained in law enforcement? If what is happening to our borders is an example of the best that law enforcement training provides then it's a dirty joke.
They can you know? And the CBP will train them for free. Look how much money you would save by driving the ilkegsls out of your town.
They know who the employers of illegals are. Why don't you demand that they bust the employers instead of demanding that Congress throw more money away on the border?
