How the government's punishing of the exposure of official wrongdoing can linger for years

Police used chemical spray Thursday to subdue protesters trying to rush the Michigan Senate chamber after Gov. Rick Snyder and other Republican leaders announced they would press for quick approval of right-to-work legislation limiting union powers.
Eight people were arrested for resisting and obstructing when they tried to push past two troopers guarding the Senate door, state police Inspector Gene Adamczyk said.
Inspector Adamczyk said the troopers used chemical spray after the people refused to obey orders to stop.
