Clearly I'm trying to make up for a post drought from the past couple of months. I'll leave the more in-depth commentary to someone who has been following this situation more closely, but it looks like the Wisconsin State Government is experiencing a wheeeeee-bit of a principal-agent problem (via Boing Boing).
Wisconsin Police Have Joined Protest Inside State Capitol
I will say that it's not immediately clear to me whether we're talking about off-duty cops only, or if we're talking about both on and off-duty police officers. If the latter are protesting that would seem to be less of a problem, but the article seems to indicate that on-duty officers are the ones refusing to remove protestors from the capitol. On the other hand, the man in the video looks more to be an off-duty officer expressing support (if his jacket is any indication).
