Dane County District Attorney Brian Blanchard said he wouldnâ??t prosecute UW-Madison for violating state law in sheep experiments, so two animal rights groups are attempting to file the criminal charges themselves. The groups – Madison-based Alliance for Animals and the People for the Ethical Treatment of Animals – are allowed to do so under a little-used state statute. They filed a petition Tuesday asking a judge to allow them to prosecute five UW-Madison officials and several researchers.
