Sadly, a very thoughtful but accurate post.
Sandy Hook didn’t result in change and neither will this event. What needs to happen? A hundred kids killed?
Nothing will happen, at least not for a generation or two or three.
The thing is that people on both sides of the divide do want change. They just support opposing paths of change. The right will propose:
1: Arming the teachers and other school staff.
2: Bullet/shooter resistant schools. No ground floor windows, no interior windows, no trees or other barriers outside the school that a shooter could use to conceal themselves and fire from cover, interior walls made from bullet resistant standards, auto-locking classroom doors triggered by central alarm system, all that. There are design proposals out there for that. Very expensive design proposals which are used mainly as a distraction because gun lovers tend to lean libertarian and are never going to want to actually pay for these designs they think we need.
3: More church, more God, more Jesus. No psychiatry - God is all we need.
4: Ban abortion - yes, they really will make that connection. They think allowing abortion signals that killing humans is okay and therefore encourages murder of adults. Yes, many conservative Christian movers and shakers really believe or claim to believe that.
5: Just more dumbazz conspiracy theories. That has the beauty of being very profitable. Alex Jones rode the blood of Sandy Hook to fame and fortune, and many other Conspiracy Theorists will do the same with this shooting.
See! They totally want things to change!
The left will propose a host of gun control laws. Background checks, red flag laws, waiting periods, time/purchase limitations (can only buy one gun a week, something like that), magazine capacity limits. This gets more complicated because they'll focus on magazine-fed semi-auto long guns, which are often used in mass shootings - but mass shootings, no matter how horrific, only make up a small fraction of overall gun deaths in America.
