Below are several photos, drawing on coverage from Jonathan Barkey and Adrian Kinloch.
Also go see this video, from RUMUR (the folks behind the Battle of Brooklyn documentary) with cleverly contrasting footage from both the groundbreaking and the "groundtaking" protest: Brooklyn Borough President Marty Markowitz vs. a faux-Marty bobblehead; Mayor Mike Bloomberg's claims of AY progress vs. Develop Don't Destroy Brooklyn spokesman Daniel Goldstein's AY critique.
Note the bogus claim from Forest City Ratner's Bruce Bender that there would be 8000 permanent jobs.
