That's Not the Batphone Ringing

It's the BS Detector going off.

Cullen Werwie, spokesman for Walker, [snip] was granted immunity
April 14.

"We don't know what exactly is involved," Walker told the Associated
Press on Friday [September 16], when asked at an unrelated event in Milwaukee. He also added: "Until we know, obviously it's a concern but again, I don't know any more details than what I've seen reported in the media outlets around the state."

The usual strategy in these investigations is to get the little fish to roll on those higher up to build a case. Werwie is the most recent recipient of immunity out of three noted here, as many as eight if you count the Gardner/Walker improprieties, and is right there at the lectern with the Governor's seal on it. Dieck and Lucht, presumably, pointed investigators toward Werwie and Archer.

How much higher can an investigation go?
