The one between three and three.
But there are a lot of crazy people that don’t shoot up schools. How are you going to pinpoint the ones that would?
By targeting the people that have been noted to be a threat to themselves and/or other people. The shooters with mental issues were also known to have made those types of threats. They need to be flagged and prohibited from buying or even possessing a gun of any type.
Of course, there will be nothing to stop them from picking up a knife and committing a mass stabbing so there's that.
