As FBI investigators sought to clarify the motive behind Wednesday's brazen shooting attack on congressional Republicans during practice for a charity baseball game in Virginia, key voices in Connecticut's gun-control debate sounded off Thursday, while the U.S. Supreme Court was scheduled to confer over a challenge to concealed-carry restrictions in California.

Outgoing Connecticut Bar Association President Monte Frank, newly appointed to the American Bar Association's Gun Violence Advisory Committee, expressed exasperation and outrage over the attack by a lone assailant armed with a semi-automatic rifle and pistol.

“I don't know, from a policy standpoint, that yesterday's event changes anything,” he said. “It's another mass shooting in a string of mass shootings that have occurred almost on a weekly basis since Sandy Hook [School, Newtown, 2012]. This time it happens to have been directed at members of Congress, which is horrible, but it's horrible whether it's directed at kids in school, people going to movies or students going to universities. I think it just reminds Americans that no one is safe anywhere, and that there is a need for common-sense gun reform to occur at the federal level.”
