If this guy gets taken out by an armed citizen it would be too much for the liberals to bear. They're already privately fuming that this guy has taken the economy away as an election issue, while they shed a fake tear for the cameras.
A sniper like this may be making more Conservatives out of Liberals than we may ever know. It is the Individual's responsibility and right to defend him or herself and his or her loved ones, including neighbors. It is not, has never been, and never could be the role of Government to do so.
Obviously we need the Federal Government to protect our borders, and we need State Government to prosecute criminals according to the Law, but there is no substitute for the Individual's right to self defense. When that right is infringed, free people become terrorized targets.
