Scott Walker has a long history of obstructing open records requests from political opponents and other people that he perceives as adversaries. I have some personal knowledge of that fact. But more specifically, Walker has been caught before not giving the actual records requested but rather producing some doctored data instead.
Back in 2004 the David Riemer campaign submitted an open records request to the Walker administration. They were trying to learn if Walker had kept one of his original promises: having "at will" employees sign pension benefit waivers. When the Walker administration received this request and realized that they had failed to keep that promise, they ran around trying to get as many waiver signatures as possible. When they finally did send records, it was only a listing rather than copies of the actual waivers (which would have shown the dates of the last minute signatures). Quite simply it wasn't what Riemer asked for in his request. Riemer later filed an open records complaint with the Wisconsin Department of Justice who had some of the following choice words for the Walker administration's open records games:
"In sum, this episode evinces a case of how government officials ought not to do business...Nobody honored to serve in public office ought to manipulate public records in this fashion -- that is the opinion of this office."
As I concluded when I chronicled my own Walker open records odyssey several months ago: "Although Walker's policy positions change with the wind, it seems that his approach to open records has not changed at all." Walker's open records games are not just costly to the requester, but they are also costly to any sense of open government in Milwaukee County.
