I think there could be a two phase prosecution.
Phase 1: Prove there was criminal collusion between elected Democratic officials and the Unions in an attempt to defraud the public.
Phase 2: Prosecute the Unions and the Democrats under the RICO statute for racketeering and seize assets.
The the State of Wisconsin could use the proceeds to close the budget gap.
Spot on. I love the way you think. RICO was the first thing that came to mind.
