Tragic Shooting of Congressman Giffords

The shooting of Rep Giffords, Judge Roll, and others in Arizona is tragic and my thoughts and prayers go out to the families affected. However, a greater tragedy will be the new guidelines that will go into effect to protect members of Congress from the citizens of our great land both.
Already we see members of both parties are too isolated from the citizens they serve. Placing additional barriers between those who serve and their constituents will only increase this isolation. Hopefully, there is some middle ground.
