The reasons we have a Department of Homeland Security are:
(1) The political answer to every crisis is MORE LEGISLATION and MORE CONTROL
(2) Can't control the terrorist threat without closely controlling our borders. Politicians are unwilling to tighten them up because it will hurt somebody's feelings or impact flow of $$$, either of which might cost them votes.
(3) Can't go after the real terrorist demographic because that involves ethnic, religious, or cultural profiling... all of which hurt people's feelings and might cost votes.
(4) Since cracking down on the terrorist threat in any meaningful way is tough and politically dangerous, the obvious answer is to crack down on YOU and ME. The politicians get to grandstand on TV and show how hard they are working in our interests, and they know it won't cost 'em votes because the sheeple will back any measure of control as long as they can pretend they are safe. Don't have to BE safe, just want to FEEL safe.
