"In cooperation with the Transportation Security Administration, gate screening of passengers is being eliminated. Passenger identification checks and screening that was formerly done at the gates will now be done at the security checkpoint. As a result, a boarding pass is now required to get through security checkpoints. An E-Ticket receipt or itinerary is no longer adequate. This change has already been implemented in Detroit and is being rolled out to all airports over the next few months. To eliminate uncertainty during this transition period, Northwest recommends that all passengers obtain a boarding pass prior to the security checkpoint. "

Just got this in the mail! This is the smartest thing the FAA has done all year... Now they just need to make it nationwide!
