The news of Scott Walker's signing of the anti-union bill was overshadowed by something even more disturbing: an allegation by State Supreme Court Justice Ann Walsh Bradley that her colleague, Justice David Prosser, grabbed her by the throat and put her in a chokehold after she demanded he leave her office.

This report is not the first documented instance of sexist attacks on liberal female colleagues by Justice Prosser. This past spring, he admitted to calling Chief Justice Shirley Abrahamson a "total bitch", but claimed it was "warrented". Though this incident did not escalate to a physical confrontation, it clearly shows a pattern of sexist behavior in Prosser. In footage made public in March,  Prosser also charged at State Senator Tim Carpenter while they served together, which while not sexist in nature does follow his pattern of violence and intimidation against liberal colleagues. If he once again claims he was provoked -- which is not unlikely, seeing as his language in the two incidents has been similar -- it will only serve to further a pattern of victim-blaming on top of his pattern of verbal and physical abuse.

Justice Prosser must resign immediately. If he does not, the responsibility then shifts to the legislature, which must impeach him as the law dictates.
