Here comes the parade -- Updated

It's better to be at the front of the parade than behind the horses, so I'm going to stake my position: I blame Scott Walker.

A Madison police officer shot and killed a 19-year-old man after he assaulted the officer, police say.

Police responded to reports of shots fired on Williamson Street at 6:29 p.m. Police confirmed an incident on the 1100 block of Williamson Street.

Madison Police Chief Michael Koval said officers responded to a disturbance call where it was reported that a person was jumping in and out of traffic, and possibly responsible for a battery.

Koval did not yet name the person killed at a Friday night news conference but Michael Johnson, CEO of the Boys & Girls Club of Dane County, identified him as 19-year-old Tony Robinson, a recent graduate of Sun Prairie high school.

Sun Prairie is a suburb of Madison, directly to the east. As usual, Ann Althouse has a good seat on the parade route:

Speaking through a bullhorn that has a "Socialist Worker" sticker on it, a woman addresses a crowd: "I want you to take this opportunity to understand and connect with [the family's] hearts. A black teenager, a black boy, was viciously killed and murdered by Madison Police Department." She also says that if things don't change, "then we will have a Ferguson in Madison." Someone in the crowd cries "We do have a Ferguson in Madison."

Here's the video, with a NSFW warning:

If you want to understand where this is headed, here's a screen shot of a Tweet that spells it out pretty quickly.

Few details are currently known, but the narrative is established

We'll come back to this when we actually know something.

UPDATE:

We may know some things. First, let's show everyone the picture that you're likely to see on the news of Mr. Robinson:

Here's a picture you're somewhat less likely to see:

A mug's game

This would be a mug shot of Tony Robinson, of Madison, following his arrest for an armed home invasion. As it happens, he was convicted in October of last year of armed robbery, a Class C felony in Wisconsin. As it also happens, he was not sent to prison.

Is this the same guy? Maybe not, but the resemblance is strong. We'll continue to watch this story.
