Where does yours come from? I actually know the answer to that question already--but are you really saying that verifying IDs are real is somehow linked to detecting terrorist threats? If so, can you please explain how?

I am not opposed to security. I am opposed to "security measures" which don't accomplish actual security, which is a reduction in threats to the transportation system or those travelling on/in it. So please explain how stopping an illegal alien with a fake ID from flying to visit his/her mother is linked to the threat that a known or unknown somebody puts something that goes boom in his/her luggage.
