WASHINGTON (AP) — Prosecutors took a hard line Thursday with demonstrators who participated in a rare disruption inside the U.S. Supreme Court, adding additional charges against them and saying disrupting the high court is different from other protests in the nation's capital. The demonstrators, five women and two men, were arrested last month after standing in succession inside the court and shouting protests against the court's 2010 Citizens United campaign finance ruling. The decision freed corporations and labor unions to spend unlimited amounts on Congressional and presidential elections. The disruptions made news not only because they were rare but because the group managed to take videos of both events and post them on their website, despite the fact that the Supreme Court does not allow cameras inside the courtroom.
