A precautionary lockdown of the U.S. Capitol was lifted after about two hours Saturday following a suicide by a man carrying a sign demanding taxes for the '1%'. The man died after shooting himself on the west front of the Capitol building just after 1 p.m., Capitol Police spokeswoman Kimberly Schneider said. No one else was hurt. Capitol Police Chief Kim Dine said the man had a backpack and a rolling suitcase, triggering an hours-long lockdown, and a sign that said something about 'social justice.'
