I regularly go into several federal buildings. Tho I get in with my gov’t ID, everyone else entering the bldgs for any reason must show a photo ID, as well as walk throught the metal detector and have their bags scanned.
I’m just curious; what is the security benefit derived from requiring someone to show a photo ID? You don’t need to state your business, you don’t sign in, your name is not recorded or anything. It isn’t all that tough to get a driver’s license. And if you are willing to submit your person and bags to a security screening, what additional value does the ID give?
