Military Base Security Once Again Under Scrutiny

Questions are once again being asked about security at military bases, after a second deadly shooting at Fort Hood in Texas.

Authorities say Iraq War veteran Ivan Lopez killed three people and injured or wounded 16 before killing himself yesterday.

Soldiers at Fort Hood were required to register their guns after the 2009 shooting by Maj. Nidal Hasan. The suspect in yesterday's shooting had not done that.

Sig Christenson, a longtime military reporter for the San Antonio Express News, joins Here & Now's Robin Young from Ford Hood with details.
