Last night, riot police drove protesters from Taksim Square, in Central Istanbul, which has been the scene of increasingly violent confrontations. Prime Minister Recep Erdogan offered to talk today, but protest leaders reportedly called that a farce. "Not just young spoiling for a fight, but also their parents with goggles and masks"… "hearing constant explosions and sirens"… "excessive police brutality"…"I was hit in the chest with a tear gas canister, others worse." Those are tweets from last night by Scott Peterson, who's based in Istanbul for the Christian Science Monitor.
