I know you're acting out concern for the children, but I don't think you're thinking it all the way through.

Airport security is designed to safeguard air travel. A shooter entering an airport could do significant harm without going through the security line.

The same is true for an ultra-fortified school with students queued up outside to pass through a narrow security gauntlet. If the goal was hurting more people, that's a prime time and target.

This kind of "fortress security" only punts the problem to the next place with relatively weaker security. It doesn't actually stop a shooter intent on doing harm.

See in this case the police on hand did nothing to stop the shooter before he entered and killed so many people.

Do we armor school buses for travel to/from school? Public playgrounds? Colleges? Private schools? Hospitals too?

Is it even possible, if these are on campuses with multiple buildings? Do we build concrete walls around them? Barb-wire fences on top?

The GOP seems happy for schools to become so bad that everyone else wants to go private or homeschool or opt out entirely. They're more than happy to turn prisons and police tech into profit centers. We can't let them degrade our schools any farther.
