With all due respect, are you trying to insult our intelligence? What attention? If by that you mean people people talking about the open border, that is because there aren't 10s of thousands of people coming over the Candian border every night. Now is it dangerous that the north is ungaurded against terrorist? Yup, but the LACK of attention to the southern border makes it more likely to be used by terrorist. I know personally that there are tons of Arabs jumping the border and going into New Mexico. Just because no bombs have gone off, does that mean they are benign? Hell no. The LACK of attention to the southern border has set up the psychological principle called the Broken Windows principle, where people contemplating a crime are more likely to commit it when they see broken windows in a neighborhood because it is assumed that the laws are not being enforced.
Everybody knows down here our laws aren't being enforced, even Osama.
Let me restate. The southern border is where the resources have been directed, because the focus was on illegal entry by Mexicans. It's only in the last couple of years that attention has been paid to putting more manpower on the northern border, where the focus is on detecting terrorists.
I'm not commenting on how effective our laws have been, I'm commenting on resource management. That's all.
