The Transportation Security Administration will no longer require travelers to take their shoes off at airport checkpoints. The rule has been in place for nearly 20 years. The TSA briefed airline industry members about the change earlier Tuesday.

A Massachusetts law enforcement and homeland security consultant who helped draft some of the first rules requiring passengers to remove their shoes at airport security checkpoints says the decision to end the policy raises concerns.

Most passengers had been required to remove their footwear at checkpoints since 2006, a policy later eased only for members of trusted traveler programs.
