"How much does that steel fence cost per foot anyway?"
I haven't put the pencil to paper on that calculation. However, I expect it would be less than the money we're now spending on housing illegal immigrants in our prisons (27-29% of the prison population?) Also less than what American taxpayers spend on paying for education and emergency room treatment for illegals. Certainly less than the hundreds of billions we've spent in Iraq keeping Sunnis and Shiites from slitting each others' throats.
I'm for reduced federal spending, but one place I'm willing to make an exception is our national security. I believe a fence would promote that and so I'd support repealing MediPill and the pork in the last Highway Bill and redirect those monies to an Israeli-type fence along our southern border.
I want to know so I can buy a foot of fence and encourage others to do the same. And get permission to erect it on private property at the border.
