Again this is the 'do nothing because we can't be 100% perfect with everything' argument. There are 2 people. One has his ID checked, the other does not. Are you trying to argue that they both have the same chance of being caught if they are up to no good? You do not think the ID check just might provide a tiny little eensy weensy chance to catch someone vs doing nothing at all? What if there is no ID, it is found to be forged, the name is on a wanted list, it is expired, etc, etc, ad infinitum.
It is not the solution, but we must do everything we can.
Then toss everyone in jail and be done with it.
Here's a better alternative: find legal solutions that comply fully with the Constitution. Allow exercise of the 2nd Amendment, and you'll find the terrorist threat change dramatically - WITHOUT infringing on the 4th Amendment.
Absolutely! And think how much safer we'd be with internal passports! Just think: if we demanded passports every time we crossed state lines (or maybe even entered cities, crossed tollbridges etc) we could catch lots more terrorists! And what about checking into hotels? Why, the possibilities are *endless*!!
How is an ID check going to stop a suicide bomber?
Why not create a national DNA database of every male so that every rape can be solved? Or a national fingerprint database of EVERYONE, not just criminals, so that all crimes can be solved? Why not prohibit all adults, except relatives, from approaching a child within 100 feet so that no child is ever molested by a stranger? Or ban all pointed knives?
