Shame on America.
Shame on the NRA.
Shame on the gun lobby.
Shame on the only country in the world with more guns than people on the streets.
Shame on a country that allows any sick in the head, angry person, of almost any age to buy a gun and to use it to shoot children and anyone else.
Shame on a country so venal that a few more dollars in the pockets of the gun manufacturers is worth pretending that the second amendment says anyone can have a gun. What the second amendment allows is the right to own a gun for the protection of your home. Even that should be subject to training, license, age, and any number of limitations.
