What? Someone stands up and says “NO, more control over citizens, more intrusiveness, more Big Brother is not the answer, and all you have is “What is your solution to this problem”?
Why not, say, Enforce the laws we have regarding the ability of a person to be in this country legally or not? Gee, that might be a good start before we start surrendering ourselves to Big Brother.
That's the whole point of trying to have secure IDs so we can identify who is here illegally, including terrorists. When someone boards a plane or applies for a job, we need to verify who they are. If they are here illegally, then deport them.
I strongly favor an attrition thru enforcement approach to illegal aliens. But you do need to have some reliable form of ID before you separate the wheat from the chaff.
