You won't wipe out Islam, but you WILL succeed in wiping out what is left of the Constitution.
This database proposal is the EXACT SAME methodology as that used by the gun grabbers. In response to a problem, be it terrorism or the DC sniper, propose a law or program that will do NOTHING to fix the problem but will place the beginnings of a Constitutional restriction on the populace. Then, when that program does not achieve the desired results, claim we have to do more of it - so the Patriot Act provisions for monitoring business transactions in excess of $10,000 will then be dropped to $1,000, then $100, and then all transactions will be included. This of course will make the database even more unwieldy for modeling or investigation, but it will get people accustomed to surrendering their private information for the illusion that it somehow improves security.
The feds don't need this system to improve security. There were State Department guidelines in place that should have denied almost all of the 9/11 hijackers entry into this country. They were deliberately overridden. There was enough information in the FBI pipeline to identify the potential 9/11 threat and act against it. It was deliberately stifled. Malvo should have been deported according to INS guidelines. He was deliberately allowed to stay. There was enough information in the sniper database to clearly indicate the Caprice as a lead candidate for the sniper vehicle. It was deliberately ignored.
The feds do not need more information - they instead need to perform a massive overhaul on their attitudes and methodologies, and use the existing information stream that is already adequate. The fact that they chose to do the opposite may be through incompetence or deliberatation - but the end result is the same - Americans are killed, and the feds, instead of looking to their own problems, use the events as an excuse to demand that private citizens give up more of their liberties.
Yup. Same as the WOD's too. Meet the new bogeyman,...Terrorism. The catch-all excuse for every budget need and every encroachment on liberty. It even neatly ties together civilian disarmament and the WOD's.
