Old enough to date Taylor Swift? Then you’re old enough to get arrested for civil disobedience.

Conor Kennedy, the 18-year-old grandson of Robert F. Kennedy, made his photo-op activism debut Wednesday, getting cuffed in front of the White House during a protest of the proposed Keystone XL oil pipeline. He was part of a larger brigade of activists, 48 in all, who got themselves arrested, including actress Daryl Hannah and his father RFK Jr. — both veterans of this kind of thing — as well as civil rights leader Julian Bond, activist Bill McKibben, former U.S. Poet Laureate Robert Hass. Also, Sierra Club Executive Director Mike Brune, whose arrest was a first for a leader of the organization.

But yes, of course, the dreamy-eyed Conor, a prep-school senior who was just another face in the fourth-generation Kennedy crowd until last summer, when he briefly dated Swift. She has since moved on, but he retains his bold-faced-name status. All were taken down to the Park Police booking station, charged with failure to disperse and failure to obey orders, and released on $100 bail, a Sierra Club rep told us.

Activists complain that the 1,700-mile pipeline, billed by advocates as a job creator across North America, would be an environmental hazard.
