And found this at Weasel Zippers, from the Weekly Standard:
David Gregory mocked the NRA's Wayne LaPierre for proposing that armed guards be at every school in America. But the NBC host seems to have no problem with armed guards protecting his kids everyday where they attend school in Washington, D.C.
... when it comes to Gregory's own kids, however, they are secured every school day by armed guards.
The Gregory children go to school with the children of President Barack Obama, according to the Washington Post. That school is the co-ed Quaker school Sidwell Friends.
According to a scan of the school's online faculty-staff directory, Sidwell has a security department made up of at least 11 people. Many of those are police officers, who are presumably armed.
Moreover, with the Obama kids in attendance, there is a secret service presence at the institution, as well.
