I'm saddened they actually are deploying this in DC. Next thing we know, they'll be in Seattle, San Francisco, Houston, other major cities... and eventually everywhere. *shudder*

How exactly would this be productive? And what bias would they use for pulling someone over if they were in a "criminal database"? Unpaid parking tickets? Unpaid child support? Also, would this work with big freeways - too many cars, some speeding, etc?

Why are they doing this anyway? Damn it, terrorists aren't everywhere like they think (or want us to think).
