If you want to make this the law, make it the law for everyone. Congressmen should not be treated differently. There are other goups of people who are subject to gun violence at a much higher frequency - I don't see anyone pushing for exemptions for them. Also, it would be good to know if there is any data that shows that having a concealed weapon helps avoid gun violence. It might have no impact. My suspicion is this is nothing more than political theatre.
