The arguments presented by Mr. Navarrette are amazingly weak. Not that one could not argue against a fence, but the reasons cited by Mr. Navarratte are hardly a case against a fence.
#1 As noted by a couple of others above $2 billion is pretty small compared to the estimated costs of mitigating illegal immigration through other means, year by year.
#2 Also as noted by another above, a well constructed fence/wall has been proven elsewhere to help. If well constructed fences do not help, why for example do military installations, businesses, and property owners build fences around their properties?
#3 Has a little bit of merit but much less than Mr. Navarrette makes it out to be. If any current illegal alien is still in the US when a fence is built there ought to be (and should the fence be built there most likely will be) provisions to allow the illegal alien to exit without fear of being imprisoned at the fence (on the way out), as well as clear paths to citizenship, residency, or gaining a work visa for those who qualify and desire such.
