In the wake of this morning’s shooting spree at an Aurora, Colo. movie theater that left 14 people dead and dozens more injured after a gunman opened fire during a midnight screening of The Dark Knight Rises, many police departments around the country are announcing they will be taking precautions when the film plays in their cities.

That includes D.C., where the Metropolitan Police Department says its officers will be “paying close attention to the theaters throughout the weekend,” MPD spokeswoman Gwendolyn Crump writes in an email.

The massacre in Colorado came during the first showing of the highly anticipated final installment of Christopher Nolan’s Batman series, a film that puts the Caped Crusader in combat with Bane, a masked terrorist with a quick trigger finger. The gunman in Aurora was said to be wearing a gas mask at the time of his assault.

Many other big-city police departments are taking similar precautions to MPD’s. In New York, Police Commissioner Ray Kelly announced that the New York Police Department is “providing coverage at theaters where the The Dark Knight Rises is playing in the five boroughs.”
