so the dude from obomba presidential center, vice president of civic engagement for the obomba foundation, the community outreach guy, says he had no idea jackson park was crucial to the migrating birds. sound familiar? just like every sneaky developer deal, every single political maneuver for time immemorial, they push their agenda through and then soft pedal it to placate any useless dissent coming after the deal is done. the time for concern is after the money men make the deal, after the sanctuary is ended. we really didn't know. who knew. we never know. like hell we don't. just follow the money, kids. 
the cool thing about politics and development and progress and all that shit is you got your clear mandate and your specific agenda and then you ain't gotta worry about any peripheral nonsense like community or nature, and you can get your money and claim your ignorance and not even have to lie.
