Man on a Roof

Austin has a sniper on the roof of a building. From the Austin American-Statesman web site:

Austin police are on the scene of a downtown building where they say an armed man is on the roof of a building near the 400 block of West 14th Street. Police have sealed off several blocks around the building; a parent at a nearby preschool said the school has been closed and evacuated.

Offices with windows (not a computer program) have closed all their blinds.
