Oh oh. It looks like actress and activist Daryl Hannah took her protest a little bit too far this afternoon. Police arrested the actor on the sidewalk outside the White House this afternoon while protesting the highly controversial Keystone XL Pipeline. Prior to her arrest, Hannah was heard saying the following:

“Sometimes it’s necessary to sacrifice your freedom for a greater freedom. And we want to be free from the horrible death and destruction that fossil fuels cause, and have a clean energy future.”

So if you have no idea what she’s protesting, let me fill you in. The Keystone XL Pipeline would transport oil from Canada to Texas. So why the protest? Many fear that it will contaminate water sources, devastate ecosystems and pose as a public health risk if completed. Sounds like something worth protesting.

According NBC, Daryl Hannah was arrested with several other protesters who refused to leave the sidewalk outside of the White House despite repeated calls and warnings from the police. She was handcuffed by police but later released after posting her $100 bail. The group she was protesting with is called Tar Sands Action and say that Obama’s decision to make or break the pipeline’s construction plans is the most important one of his career.

This isn’t Daryl’s first arrest for protesting. She was arrested in 2006 when she helped protest the bulldozing of an urban community garden in Los Angeles and in 2009 for protesting against mountain-top removal in West Virginia.
