Ten years after the 9/11 attacks, U.S. leaders continue to try to find ways to protect the country from the threat of terrorism. In one program cited as a model, security guards at popular places such as shopping malls and sports stadiums try to spot "suspicious persons".

NPR's two-part report from investigative correspondent Daniel Zwerdling focuses on an acclaimed program at the Mall of America in Minnesota. The joint investigation by NPR and The Center for Investigative Reporting raises questions about whether private security guards are harassing innocent people as they label them as "suspicious", and whether there is sufficient cause to keep the reports filed in local and national law enforcement databases, where they might be stored for decades.

The radio reports air Sept. 7 on All Things Considered and Sept. 8 on Morning Edition. In addition to the NPR segments, an exclusive TV piece airs Wednesday, Sept. 7 on PBS Newshour, and the reports will be available online on the NPR, PBS, and The Center for Investigative Reporting websites.

Work is nearly complete on the first leg of our project to move KGOU's Oklahoma County signal to another tower in northeast Oklahoma City. Our contracted tower crew has installed a new antenna 640 feet above ground level at the new location. Chief Engineer Patrick Roberts has been working with the crew, and snapped some great photos, which we've posted on our Facebook page.

The next leg of the project involves moving the existing transmitter and the building it's housed in to the new location. We've run into some delays in this part of our plan, but we're working to get it wrapped up quickly and with a minimum of signal disruption. Stay tuned for General Manager Karen Holp's progress reports from the Manager's Desk over the course of the project.

Walter Reed Army Medical Center in Washington, DC has permanently closed after providing care for the nation's war wounded for more than a century. A government commission charged with closing military bases voted to close Walter Reed rather than to fund renovations.

As operations move to new facilities at the National Naval Medical Center in Maryland and to Fort Belvoir in Virginia, NPR News looks at Walter Reed's history, the medical treatment of U.S. troops, and the financial and logistical outcomes of closing the hospital. The six-part series airs next week, Aug. 29 - Sept. 2, on Morning Edition and All Things Considered.
