Two rallies by gun rights celebrants and anti- government polemicists are planned Monday on both sides of Washington's Potomac River. They will invoke the Second Amendment and the Battles of Lexington and Concord. A more apt, and tragic, anniversary to keep in mind is the Columbine school massacre of 1999. Eleven years later, and Congress has failed to close the gun show loophole that made the carnage possible.
