Earlier, The Local tweeted and reported from the scene of the National Day of Protest to Stop Police Brutality, Repression and the Criminalization of a Generation. Now see video of the demonstration as it moved from Union Square, down East Eighth Street, to Avenue D – near to where Makever Brown died on the FDR Drive while fleeing the police. We spoke to the march’s organizers and attendees, including Shamar Thomas, a former Marine whose yelling at N.Y.P.D. officers last week received widespread attention, and Jean Griffin, the sister of David Glowczenski, who died after Southampton police used a Taser stun gun on him in 2004.
