New York police report that 1,000 protesters were arrested Tuesday:

Nearly 1,000 protesters were arrested across Manhattan on Tuesday as swarms of activists massed in the streets for marches to the site of the Republican convention - by far the biggest day of arrests since the demonstrations began last week.

There were no immediate reports of violence, but police Commissioner Raymond Kelly said officers showed "great restraint in the face of relentless provocation" by the protesters.

No violence? Then why were they arrested? Wasn't it just last week Mayor Bloomberg was offering shopping discounts to non-violent protesters as a welcoming gesture?

Heightened security against the protests has turned Manhattan into a crazy-quilt of barriers, heavily armed police and street-corner activists.....Outside the New York Public Library, in the streets near the famed Herald Square and at the site of the fallen World Trade Center, demonstrators pointed themselves toward Madison Square Garden and promised to get their message across that they want President Bush out of office.

On the library's stone steps, hundreds of protesters gathered for the march. Verbal confrontations erupted as police moved them away from the library's front door and wrapped the block in orange netting, and about 75 people were taken into custody before the crowd thinned out.
