Democrats in Wisconsin feel free to make threats without bothering to hide their identity and it's not hard to guess why.

WI Attorney General Releases 100 PAGES of Documented Threats Against Lawmakers During the Budget Negotiations. “A surprising number of even the most vile messages came from readily-identifiable senders.”

As Prof. Jacobson has asked in the past, “Why do these people, many of whom are professionals, feel no fear in expressing such death wishes in the open?” Because they don’t expect to face any consequences. And so far, most of them haven’t.

During the Wisconsin protests, there were 2 occasions when written threats were directed at Meade and me, and, in both cases, it took almost no time to identify the person making the threat. The first one said I "need[ed] to be shot in the head" (for making a video of city salt trucks circling the Capitol Square blowing horns in apparent support of the protesters). The second one described a campaign to harass Meade and me and drive us out of Madison, where we have no right to live. Even though we called the police in both cases, and the police duly took down a report, nothing seems to have happened to the culprits.
