Apparently during the recent protests in Madison, someone scattered .22 rounds around inside the capitol building. I read about it in some blog comments somewhere so I did a search. Of course I can only seem to find mention of this event on minor news sources. Imagine if this had been a Tea Party event - and ammo was found scattered around? It would be front page news on the NYT.
Clearly this is a hint of violence. The message being sent is “We’re going to start shooting.” The wonderful thing about messages like this - is that messages can be sent in both directions.
