Because it has moved way beyond protests. Everyone agrees that school shootings are bad. Legislation has been passed. Policies have changed. Schools have changed their security tactics. There have been years and years of meetings across the country with school administrators and boards talking about how to improve safety and navigate these issues, and then the schools themselves implementing new practices.

If you are looking around and saying that because people aren't waving sign on street corners, then nobody cares, then you have utterly missed a couple decades of dedicated efforts by many people working around these issues.

The fact that shootings still happen is tragic. But it is not because people are just shrugging and saying they don't care.

Well they happen in schools and children don’t vote. If this had been a wave of senior center shootings, something would have been done a long, long time ago.
