He was the alleged mastermind of the mid-April Boston Marathon bombing that killed three and maimed 264, but the anti-gun lobby organized by New York Mayor Michael Bloomberg and Boston Mayor Thomas Menino has a different label for Tamerlan Tsarnaev: gun violence victim.

It happened Tuesday during dueling pro- and anti-gun rallies in New Hampshire where liberals are mounting a campaign against Republican Sen. Kelly Ayotte for voting against the recent Senate legislation to expand background checks.

Bloomberg's and Menino's Mayors Against Illegal Guns movement arrived at the Concord event with their bus. According to reporter Tim Buckland's story in the New Hampshire Union Leader, the anti-gun organizers read the names of those "killed with guns" since the December shootings at Sandy Hook Elementary in Newtown, Conn.

With the group's "No More Names" bus in the background and parked in front of the state capitol plaza, the reader flipped through the names of gun violence victims, including Tamerlan Tsarnaev.

A pro-gun protester shouted, "He's a terrorist," according to the Union Leader.

Not only did Tsarnaev allegedly plot the horrific and deadly terror bombing near the finish line of the annual Boston Marathon on Patriot's Day, but he was later shot by police in a wild chase during which grenades and other explosives were tossed from his car.

Afterward, Boston Police Commissioner Edward Davis said, "We believe this to be a terrorist." He added, "We believe this to be a man who came here to kill people."

The "No More Names" bus tour kicked off June 14. Bus stops are aimed at generating new public support for gun control legislation. Their website on Wednesday said that "6,169 AMERICANS HAVE BEEN MURDERED WITH GUNS SINCE NEWTOWN."
