A Birmingham man is among many who say the Transportation Security Administration's tactics are aggressive and invasive.

Chris Key will take part in "Opt Out and Film Week." It's a national effort where people who share his views will voluntarily undergo pat downs at airports. They will videotape the encounters and post them online.

"People don't realize when they give up a little bit of liberty for security, you lose both," Key said.

"TSA takes its mission to protect the safety of the traveling public seriously and our officers will continue to uphold our high standards of professionalism during the busy holiday season and every day throughout the year," TSA said in a written statement.

Key says the videos will show the pat downs are borderline sexual assault and are unnecessary for passenger safety.

"We are reminded of the need for constant vigilance with instances such as the Christmas Day 2009 suicide bomber," TSA continued. TSA respects passengers right to exercise freedom of speech as well as the rights of fellow travelers trying to get to their destination safely and without unnecessary delay."

"People have inalienable rights given to them by God and are supported by the Constitution and these things are being violated," Key said.
