UPDATE True, no one hurt, but see tonight's NYT story on how it could have been much worse. 1) he had an AK-47 and seemed like he wanted to kill many 2) only a brave school staffer kept him from maybe getting started before police came 3) he had explosives in his car.
Earlier: Reports from DeKalb, Ga. of shots fired at McNair Elementary School--and an "active shooter" still "on campus" at the charter school or missing. Local TV report. SWAT team there. No word on injuries yet. A little more here. Students evacuated. Update: Report of one person in custody. He had "demands." Students all accounted for--though unconfirmed.
