Well I profoundly disagree. In time, Americans will sort this out. They'll restrict what guns can be owned, and who is entitled to have them. The fact that it is difficult, and won't be done quickly or in one go, doesn't alter my optimism. You pessimists are entitled to your view, but it's hard to separate that attitude from those of the NRA supporters.
Here is the evidence that will not happen. A list of school shootings in the USA. I am going to concentrate on shootings where kids get guns to kill other kids. Many in the list are college and university students and involve teachers, I am not including them.

The first massacre attack by pupils on other pupils was the 1998 massacre at Westside Middle School whereby;
"13-year-old Mitchell Johnson, and 11-year-old Andrew Golden, killed a teacher and four students, and wounded ten others, as Westside Middle School emptied during a fire alarm intentionally set off by Golden"
So, 5 dead, 10 injured. I don't know why that did not get a huge amount of attention. Look at the ages, they were kids. Maybe it was because pupils had been shooting fellow pupils for a number of years already, but it was one or two shot at a time. Within only 2 months, there was another multiple victim shooting;
"After killing his parents at home, 15-year-old Kip Kinkel, drove to Thurston High School, where he killed two students and wounded 23 others."
It was the next year, in April 1999, that a school massacre by a pupil on other pupils finally properly hit the headlines;
"18-year-old Eric Harris and 17-year-old Dylan Klebold, students at Columbine High School, killed twelve students and one teacher. They injured 21 additional people, and three more were injured while attempting to escape the school."
It took Columbine to happen before the headlines really hit and that shows how conditioned the USA was to kids killing kids and not reacting. Did Columbine cause a change, whereby action was taken to get a better control of guns? The answer is an emphatic NO.
Have you even heard of the next massacre? It was in 2005;
"16-year-old student Jeffrey Weise, killed his grandfather and grandfather's companion at their home, where he had been living, at the Red Lake Indian Reservation. He drove to Red Lake Senior High School. Armed with his grandfather's police weapons, Weise killed five students, one teacher, and one security guard, wounding seven others, before committing suicide"
Killing at home, getting guns and travelling to a school to kill. That was a template for;
"Sandy Hook Elementary School shooting: 20-year-old Adam Lanza, killed twenty-six people and himself. He first killed his mother at their shared home before taking her guns and driving to the school. Lanza brought four guns with him. He killed twenty first-grade children aged six and seven during the attack at school, along with six adults, including four teachers, the principal, and the school psychologist. Two other persons were injured. Lanza then killed himself as police arrived at the school."
Did that make a difference? The answer is another emphatic NO. Indeed,one of the most striking reactions was not to tackle gun control, it was to claim the shooting was faked. Far more time was spent arguing over whether or not the children had been killed or not, than was spent trying to get a consensus and act to restrict guns from people like Adam Lanza.
Kids are getting guns and massacring other children.
By now it is clear, NOTHING is too shocking for the USA. NOTHING will cause Americans to unite and at least try and get agreement on how to stop kids with mental health and anger issues getting guns.
Now, evidence the hope you claim will happen.
