If that helps government to keep America safer why not? As long as CBP does not hold you up on POE for long time.Hopefully they will be prepared to handle it timely and properly.
See, that's that biggest problem about this whole thing. Every single time a controversial measure is implemented, the government cries national security, and everyone accepts it. The NYPD has installed "security" cameras in some of NYC's neighborhoods. Soon enough, if we assume the attitude of "if it keeps America safe, why not", we'll all be implanted with RFID chips, so that the government can keep track of our every move. Don't get me wrong, I'm not against security. I'm just against government trying to butt in to every aspect of our lives and disguising it as security.
