If flags must be removed because someone finds them offensive, this implies that everything can be banned, since pretty much everything offends somebody. Would they ban Obama bumper stickers if they offended anyone?

rgallagher asks if the previous administration stopped an attack before it occurred. Yes it did. Enhanced interrogation techniques got captured terrorists to provide info that prevented a big attack on Los Angeles. Obama is now investigating the CIA agents who got the info that saved many American lives. When the next attack comes, you can wonder if we might have prevented it if Obama hadn't handcuffed the CIA.
