Wired has the story of a man we first heard tell of from local anarchist Paul McCarrier after the G-20 protests: a man who used Twitter to communicate and help protestors rally against an organization he believes is a threat to human rights.
No, this isn't those Twitter-fueled Iran protests, which the State Department famously asked Twitter to delay site maintenance to support.
Yesterday in the late afternoon and evening, a march was broken up by police with tear gas and sound cannons (see below). Some of the marchers regrouped and kept going; they were met by police firing rubber bullets and tear gas and beating marchers with batons, according to direct on-the-ground information we have, corroborated by press releases and published reports.
G-20 protestors have been tear gassed by police, according to Paul McCarrier, who was among the marchers in a parade slated for today. The march started around 3:15 and by 3:20, the police had tear gassed the crowd.
They have also deployed a sound weapon, McCarrier reports.
Riot police have been a heavy presence throughout Pittsburghall week, even showing up in force at a community picnic in a local park.
