Looks like Occupy D.C. protesters will have to find somewhere else to lay their heads at night. Police have been taking down tents and other structures at the encampment—formerly known as the "Tent of Dreams"—in McPherson Square early Saturday morning, days after the National Park Police ordered the protesters to stop camping. Police entered the encampment around 5:30 a.m. and began collecting pallets and other items from the campers. Four arrests have been made, but officials are mostly focused on taking down the campground. Police insist they're not evicting the protesters, who are allowed to stay there during daytime hours.
