U know it just seems like security in the US is run by a crowd of amateurs and they haven't looked at what works and doesn't work in other countries that have faced similar terrorist threats. Vague alerts and warnings that almost seem designed to alarm and confuse the populace, either by intent or by incompetent.
I think the assumption here is that segments of population shopping at Wal-Mart somehow are just the right people to collaborate with DHS. I am not surprised, but what is scary is that those at DHS have recognized that as well...
