About a month ago I received this pdf [1] (1700+ pages of email records) of Chicago's office of the mayor after about three months of resistance. Prior to that, it took a year and a half and a law suit to receive one week's worth of Chicago's mayor's logs [2] through Chicago's IT department. To my knowledge, prior to this work, records in volume have been impossible to get due to asinine rejections. The amount or resistance (and holy shit was there a lot) led me to run several chains of FOIA requests to gather bulk communication records.
Of note in the call records are many private investigator calls. I haven't had much chance to go through the email records and could use some help if anybody's interested.
