Better or worse has nothing to with it being practical as well as getting everyone to agree and having the money and resources to do it. Many things in this life boil down to X would be better than Y but still isn't gonna happen.  It would be better if we lived in a world where a 6 year old couldn't get access to gun in the first place, but we live in truly crazy times

I bet putting metal detectors and security guards on every school in the US would be a drop in the bucket compared to the total US military budget. 

In the grand scheme of things it feels like a problem that could be solved by throwing money at it, if, you know, you don’t want to solve it with gun control which seems to work in the rest of the world.
