ST. PAUL, Minn. The bright white light of flash bombs can be seen everywhere among the scattering crowd. Loud explosions of concussion grenades mix with the lighter, metallic tinkling of tear gas canisters bouncing along the pavement. Lines of police dressed in full riot gear stretch beyond the sulfur-green clouds of smoke bombs. Shouts come from all directions in the darkness, suddenly lit up like a war zone.
"What are you doing? We're peaceful!" some people scream.
