Just finished this book "The Violence Project" which was an in -depth investigation into mass shootings. They got as much data as they could about mass shootings in the USA over the past 60+ years and put it into tables so that they could look for commonalities, trends, etc. to help understand mass shootings and how to stop them. They also reached out to a bunch of living mass shooters to try and get the story from the people who did it themselves.

Hardcore gun rights people aren't going to be a fan of the book because it does make the argument that the ease of access to firearms as a part of the problem however it really isn't just another book saying guns are bad. It outlines a number of other non-gun related problems that seriously contribute to this problem to give a comprehensive view.
It mentions weaknesses in mental health care systems both in school and in general
It mentions weaknesses in the ability of law enforcement or authorities to respond to warning signs
It mentions weaknesses in teachers and employers failing to recognize that someone is in crisis.
It mentions how giving shooters such notoriety is making the problem worse. It mentioned how so many shooters were fans of previous shooters. It points out how the USA had a wave of serial killers when it became a hot news story but then died back down when the media stopped giving it so much attention.
It covers how many of the shooters go down deep dark rabbit holes on social media that feed conspiracy theories and encourage/praise shooters.
One of the main thing the book really tries to drive home is that we should see these shooters as being in a state of crisis. So many of the people who did these shootings had long histories of traumatic lives (abuse, sexual abuse, parent suicide, etc.) that were often prefaced by a recent significant incident like being fired or kicked out of school. It stresses recognizing people with that type of trauma and getting them help as someone going through a chaotic event in their life.
The book explains that these shootings can usually be viewed as a form of suicide since most plan or expect to die and talks about how they are deaths of despair when people stop finding meaning in life. This is a problem facing young men these days (that sentence is my addition to the topic)
Lots of interesting statistics, some we (gun rights advocates) would like, and some not so flattering to our position but facts are never usually all on one side or the other.
It didn't have any magic bullet to stopping mass shootings and there were a few angles I wished they went deeper into but overall I think the book is a good one to read about the topic. I think they tried to do an objective look at the issue.
