FYI, there is a group known as "No More Names" which is an action group of Bloomberg's Mayors Against Illegal Guns (MAIG) that is sponsoring a "bus tour" whereby they send a group of people to towns around the country to read the names of people killed by guns. They have indicated they'll be in Blackburg, VA tomorrow and down in Raleigh as well as Atlanta so far. They don't release all the dates ahead of time because they don't want protesters to ruin it for them but that has not worked.
