911 transformed our lives here in the United states and abroad. We will never be able to go back in time.
I like watching old TV shows especially cop shows. In those pre 911 shows sans cell phones and airport security everyone had to use a pay phone to make a call. In those shows the cops could chase the bad guys through the airport without worry of being stopped by security. Remember the OJ ads ofhim running through the airport? You couldn't do that type of ad today.
Life was different pre 911. There was hardly any joint ventures between law enforcement, each city saw their turf as theirturf. Feds didn't work with locals and CIA didn't work with FBI and the like. Today we have joint ventures and sharing of vital information all of which have made us a bit safer but also a bit more paranoid.
10 years and we still have brave men and women in the Middle East fighting against Islamic extremists who terrorize those who don't support their world views. The very same type of individuals who flew planes into the World Towers and Pentagon and were heading for the White House but were stopped mid air by brave people who did what they had to do to stop them from more destruction.
Trillions of dollars are spent world wide on counter terror procedures and will continue to be spent in the foreseeable future. Money that could have been spent elsewhere. Indeed 911 transformed our lives and continues to transform our lives.
