SAN FRANCISCO (KCBS) -- Mayor Gavin Newsom Wednesday called for the addition of full body scanners at every security checkpoint at San Francisco International Airport.

SFO executive director John Martin, San Francisco Police Chief George Gasc�n and Mayor Newsom stood side to side at the airport's International Terminal which has been using a full body scanner for about a year to randomly check passengers for concealed weapons and explosives. Newsom said the devices use sound state-of-the-art technology that he would like see at every passenger screening location.

"We've really been a testing ground for this technology successfully. That's why we think we should be uniquely positioned front and center for any subsequent federal appropriation," said Newsom.

The mayor acknowledged concerns about privacy and criticism from civil liberties groups but said passengers don't seem to mind and not a single complaint has been received.

According to KCBS you support the installation for full body scanners at SFO in part because "not a single complaint has been received." If that is still the case please consider this your first complaint on the issue. As an individual who flies through SFO on a fairly regularly basis I strongly oppose this initiative. Full body scanners are intrusive, expensive and, most importantly, ineffective. It has been repeatably shown that full body scanners almost certainly would not have detected the bomb carried by Umar Farouk Abdulmutallab and it is common knowledge that al Qaeda is already practicing defeating these devices. What we need is better intelligence gathering and cooperation, not more intrusive and pointless security theater. Short of subjecting all travelers to a body cavity search it is impossible to ensure that no one can ever get a bomb on a plane so, in my view, by the time a terrorist reaches the airport checkpoint the system has already failed.
