TSA began making passengers remove their shoes to screen for explosives in August 2006. The policy was implemented nearly five years after the 9/11 attacks and when Richard Reid, who is known as the “shoe bomber,” used matches in an attempt to ignite explosive devices hidden in his shoes on a flight from Paris to Miami.

Secretary of Homeland Security Kristi Noem will announce Tuesday afternoon that airline passengers no longer have to remove their shoes while going through security checks run by the Transportation Security Administration.

The Transportation Security Administration will now allow passengers to leave their shoes on, but security screening is still in place at airports.

Now that the much-hated "shoes off" policy has been officially ended, Bruce Schneier sees other parts of the TSA's "security theater" that serve little to no purpose.
