I suppose the answer is always yes, but....
The new "IDs" used by AD, GSs, and contractors are very high tech. Known as CAC Cards, they have multiple high tech devices (embedded chip, magnetic strip, and a barcode) that provide multiple redundancies for security. It's not just faking a card and laminating it. I need mine just to log onto my computer and to send email.
(Not Gamecock, just a sample found on the internet)
The issue here, IMHO, is they are trying to make the whole screening process at airports idiot proof. The weakest point in the system probably are a few TSA screeners. Take the thinking out of the process and they can't screw up.
A friend of mine who is a CSM in the Reserves also works for the TSA. He says he has busted a few folks in uniform that were posing as military. He pulled this one gal aside and started asking a couple of questions - she couldn't even identify her unit patch, had no ID card and no orders. She missed her flight.
Thank you for your replies.
