Do you feel safer? I don't. Lots of Texans don't have passports who aren't a security threat, but all the 9/11 hijackers had fake passports that let them through security. So what's the point of this, exactly?
Generations of Texans until now could visit the Mexican border without registering with the feds or having your travel recorded on a visa stamp (many people go back and forth quite frequently, after all, including regular commuters). So this adds more bureaucratic steps in the border crossing process and likely clogs up the borders in the short term while they work out the kinks and accommodate delays. If this improves security, though, I wish somebody could tell me how.
UPDATE: Frequent crossers can apply for a special "passport card" that's only good for land crossings, not air travel, which tracks border crossing by RFID.
RELATED: It's not just American tourists and maquiladora suppliers who need to cross the border. Al Jazeera, of all places, has a short piece on the "hundreds of thousands of lower and middle class Americans [who] have crossed the southern borders to Mexico, in search of everything from prescription drugs to alternative cancer treatments, still illegal in the US." Having once been hospitalized while traveling in Mexico, my experience has been that you can get pretty darn good healthcare there if you're able to pay, and at mind bogglingly low rates compared to US healthcare costs.
