Mayor Bloomberg’s press conference at City Hall on Monday had the feel of a historic event. In the wake of the Newtown massacre, the question in that packed room seemed to be, “Is this his moment?”

Because Bloomberg has emerged as the most prominent gun control advocate in the country. But although he put forth concrete proposals — like requiring background checks before all gun sales, and banning assault weapons — the Mayor hardly sounded confident that anything would happen, even this time.

"If this doesn’t do it, what is going to?" he said. "But that doesn’t mean we still shouldn’t try."

The most hopeful person in the room, oddly enough, was one of the family members of gun violence victims that Bloomberg surrounded himself with during the news conference.

Sandra Moses lost her son Steven 25 years ago and said that after an initial period of making public speeches and fighting for gun control, she gave upthe cause. She said it felt pointless, and sensed early on it would take an event of great, almost unimaginable magnitude to change America’s mind about gun control. She now believes the shootings at Sandy Hook elementary rise to that level, and that change is set to unfold.
