Daryl Hannah donned a familiar accessory outside the White House today -- HANDCUFFS -- after she was arrested during an oil pipeline protest. The actress-turned-activist was busted with several other protesters -- when they sat on the sidewalk in front of the White House and ignored three requests by police to move. Daryl's an old pro when it comes to getting arrested -- saying, " 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." Hannah was famously arrested after she stopped traffic in West Virginia in 2009 -- blocking a busy street during a protest over mining practice.
