Many believe we should be putting our high-tech industry to work protecting our borders. Actually, I agree we have the technology, when it is too windy for those Aerostats, use the drones or unmanned aerial vehicles for surveillance and technology with infrared and the Cactus fake trees. We could set up zones of pain with sound or microwave, if you hit one the system warns you in several languages to go back, you keep going pain increases? Non-lethal.
We have technology to sniff out drugs at checkpoints, screen instantly for Hepititus, TB and such. We can verify with Facial Recognition, ID card, RFID locator on card, finger print image. You could come and go freely once you were set up. $100 fee to register. Everybody leaves first (illegal remember) and then comes back with blessing and work pass, with business card and name in-country of employer. Probationary period can be applied to citizenship on a 2-3 year plan.
We can be fair and keep the bad apples out. AZ 35% illegal aliens in prison now. Keep out drugs and MS-13 gangs and any would be International Fundamentally Deranged Terrorists. We can do this, but the US Congress and Senate have weak leaders who are afraid and they are bunch of scoundrels too boot. Literally boot them out. Consider all this in 2006.
