At this point, the reason liquids can be brought through is the exact same as taking your shoes off, removing your computer... SECURITY THEATER. Plain and simple. Until enough of the country and/or Congress can tell the TSA once and for all that Security Theater isn't making us safe and is simply a waste of money, these things won't change. Opt-out day was barely a blip on the radar.
Ron Paul getting up and arguing against these procedures, as well as NoS, invasive pat-downs... is not enough. We need numerous Dems and Repubs in both Houses to get up, and that requires a concerted effort by FFs and not alike; FTers and not alike.
Spread the word: TSA must go! We need smart security that keeps us safe!
