Well, here's a window into why they think that way:
"Hey nothing personal when I shot you, it was just politics."“The security guard here is a hero, as far as I’m concerned,” D.C. Police Chief Cathy Lanier said. ”He did his job. The person never made it past the front.”The guard, who was not identified, was shot in the arm and was conscious after the shooting and was in stable condition. The gunman, who also was not identified, was being questioned by the FBI, sources said. Sources said he is in his twenties....Sources told Fox New that after guard took away his gun, the suspect said, "Don't shoot me, it was not about you, it was what this place stands for."
No wonder they want to take everyone's guns. If they had any themselves, they'd start shooting the local GOP offices up. Oh, wait.
My big reason to oppose more gun control laws used to be that I think that the proponents don't have the slightest idea what they're talking about and that the new laws will be ineffective or counter productive. Now I'm starting to think that there's simply no reasoning with a wild fire, and that all proposed gun control laws should be rejected out of hand, without consideration, because they are presumed to be malicious in nature until proven otherwise.
I would support criminal control laws doubling sentences for politically motivated shootings. How's that for a compromise?
