It is indeed the boys in the picture below.

Another point is that the ones above aren't alone.  They are working as a team.  They are trying to overcome obstacles (mostly imagined) and getting stronger.

Every school shooter is shouting, "look at me, do not ignore me".

And what does society do?  Drugs them and ignores them some more.

You can tell that boys who grew up with toy guns, then BB guns, then a 22... have never gone on a school shooting.  Because, these boys, if they ever decided to shoot up a school, would build themselves a blind and pick off kids from a distance.  The numbers of fatalities would be WAY higher.  But, we can't talk about such things.

The NRA gets the blame, when they should actually get the praise.
