This isn't a matter of "not 100%;" it's 10% or less. To say that the reason border security is so lax is because there are higher priorities when Bush has actively worked against border security is simply not honest. Remember 245i? How many pilots are armed yet? Did he do anything about Mineta dragging his feet? Remember how the ban on Mexican trucks was lifted? You do know that there are large numbers of Arabs buying their way into the US through Mexico, don't you? Now just how did those highjackers manage to enter and stay in this country and how did they manage to take over those planes?
The assault weapons ban thing is a political red herring and anyone with any sense knows that, except those who want to "divide and conquer" the conservatives, splitting up the Bush support.
Selling out a Constitutional principle in order to appear politically moderate can just as easly backfire if the AW ban gets attached to a bill Bush really wants. He didn't have to say he would simply sign it, especially when we both know that the scope of the reauthorization bill goes far beyond the original legislation. Nobody made the President make that blind commitment.
The reason I mentioned the AW ban and armed pilots wasn't just some unrelated pet issue. It's a matter of fundamental trust in the American people to manage homeland security instead of turning us into a police state and expecting inspections and searches without probable cause to do the job. That's what the founders of this country intended and it's the only thing that will really work, or does your memory of how the DC snipers were apprehended somehow elude you?
