Last I checked overstaying a legal entry visa meant they were illegal. Illegal Immigration is hardly a false threat clawrence.
I understand that many threats loom today and I will settle on the thought that AmeriCANs are able to address more than one threat at the same time.
Are you going to participate in the May Day 'protests'? ;)~
No, and I also disgaree with your threat assessment. I'd rather keep ALL terrorists out, legal or illegal, and wasting our time with the millions who are not is not a wise allocation of resources.
