Its about school shootings.
If Maine and Idaho etc. have different rules than other states it might be relevant to compare the difference in the amount of school shootings.
It's about shootings. Or more generally, it's about violent crimes. You apparently want to narrow it down to school shootings and only school shootings, but I'm not sure why.
Of course, the point has been made that there are some states which have more lax rules on firearms which have lower rates of crime than states that have stricter rules. Because of this, some people might want to examine other possible factors in gun violence, as opposed to simply being satisfied that it all comes down to lax gun rules and leave it at that.
Im not saying that it will be easy, things rarely is in politics, because there are many people (politicians) with their own agendas. But it is remarkable that the US have so many school shootings compared to everyone else, and I don't think any other country have a gun law as you have in the US, so it seems like an obvious place to start making some changes. The rough part is convincing others about it, no disagreement there. But at least in my opinion the first step is to get rid of the lobbyists or at least much better rules, because they are not speaking for the public interests, but are speaking for the various organizations and their agendas.
In 2021, the total lobbying spending in the United States amounted to 3.73 billion U.S. dollars. This is an increase from the 3.53 billion U.S. dollars spent on lobbying in 2020.
Companies and organizations don't throw this amount of money after something if they don't also benefit from it one way or another. And its not just an issue in the US.
When advocating for any kind of political change, it often comes down to priorities and what people feel is the most important issue to solve. For some people, it's gun violence. For others, it might be abortion laws. Still, others might emphasize LGBTQ issues, as their primary issue of focus. Then there are those who care far more about foreign policy than anything to do with domestic politics. Climate change, immigration, border security, crime, terrorism - all of these issues tend to be at varying levels of priority for people.
For me, it's more about the well-being of working people, availability of affordable housing, healthcare, education, and other areas of the socioeconomic system which have been badly neglected in recent decades.
So, we all have our own different areas of focus and priority. That's what struck me a number of years ago when I was reading about the Occupy Wall Street movement. There was no singular cause that everyone was focused on. It was more a cacophony of different groups hawking their own pet cause, and there was no real coordination or focus. So, it just kind of fizzled out.
It's even worse at the national level, as you've hit upon the problem with lobbyists and special interests and how much they spend to gain influence in the inner circles of power. Big money, big business, corruption at all levels of government. Politics is a dirty business, as my grandfather always used to say.
