Mass Show of Peaceful Dissent Soon Makes Violent Descent

Bolstered by emergency help from the Minnesota National Guard, police in St. Paul arrested 284 people Monday after outbreaks of violence and road obstructions linked to rogue bands of demonstrators among an otherwise peaceful throng estimated at 10,000 people.

The demonstrations, on a steamy first day of the Republican National Convention, began with block after block of marchers -- far fewer than the 50,000 some had predicted -- chanting and peacefully waving signs on downtown St. Paul's narrow streets. As the day wore on, the carnival atmosphere turned ugly.
