On Friday, the NRA spoke out for the first time since the shootings, calling for armed police officers to be stationed at schools to stop the next killer "waiting in the wings."
Wayne LaPierre, CEO of the nation's largest gun-rights lobbing group, said at a Washington news conference that "the only thing that stops a bad guy with a gun is a good guy with a gun."
Among those criticizing the proposal is Jackie Rowe-Adams, who founded the non-profit group Harlem Mothers Save in 2006, after her son Anthony was shot and killed in 1982 and her son Tyrone was shot and killed in 1998.
She confronted LaPierre at an NRA convention earlier this year.
"I said 'Why are you not supporting gun legislation, why are you allowing easy access to these guns?'", Rowe-Adams said.
"His assistant gave us his NRA card to call, and we've been writing letters and he never got back to us."
Now she is adding her voice to the chorus of national criticism of LaPierre and his proposal.
"He put the blame when he was talking to me on everybody, and now it's just another excuse," said Rowe-Adams.
The head of New York City's police union, Pat Lynch, also criticized the NRA Saturday, saying they missed the mark.
"It's not that there's not a security guard in that school," said Lynch. "It's that someone is bringing an assault rifle as if they're going to war."
"Take care of gun enthusiasts and hunters, and give the answer that's appropriate for that lifestyle, and then say by the way, there's no need for these weapons on the streets of Connecticut, or certainly not on the streets of New York.
The firestorm against the NRA will likely continue.
But many are left wondering, while the NRA and gun control advocates engage in this ongoing national debate, what could be next.
