And an email landed in my inbox from the White House with appropriate words from President Barack Obama. It was time, he said, for "rejecting atrocities like these as the new normal and renewing our call for common-sense reforms that respect our traditions while reducing the gun violence that shatters too many American families every day".
There was another anniversary this week. On September 15, 1967, President Lyndon Johnson sent a letter to Congress imploring it to pass new gun controls. One year earlier, student Charles Whitman opened fire at the University of Texas, killing 13 people. For 50 years this has been happening.
As Time magazine points out this week, the language used by LBJ then, and by Obama last year when he tried to push through similar laws after the Newtown elementary school massacre, is interchangeable.
Both men stressed the limited nature of what they were seeking. Johnson said his law, "interferes neither with sportsmen nor law-abiding citizens with a legitimate need" to own guns. Of his, Obama noted: "Nobody could honestly claim [the bill] infringed on our Second Amendment rights".
A version of the LBJ law did get through. But Obama's efforts have come to nought. What will it take to prick America's coma on guns and the Second Amendment? I was in Newtown after its school shooting and I allowed myself to think then that the moment might finally have come. Then the National Rifle Association did its thing. Nothing was passed.
Maybe the girl-with-the-Uzi incident could have done it because it so vividly highlighted the gulf between gun-owning rights and common sense. Yet the forgiveness video will close debate down.
If only those children had said: "This is crazy, why did our father give you that Uzi and why did the range allow it? Why does the law allow it?" The video closes with them holding up signs spelling "L-O-V-E". They should have spelled out "S-T-O-P".
There is some good news; Bullets and Burgers has voluntarily tightened its rules so only guests who are 12 years or older and at least 5ft (152cm) tall will be allowed to play with Uzis.Independent
