I was writing a piece today about gun violence when news broke that the FBI was releasing 1500+ pages of documents about Sandy Hook. They are available here.
Experts in the case say there's nothing especially new here, but I haven't read them all before. Two things remain clear.
1) There were lots of warning signs and missed opportunities for interventions of all sorts.
2) Without the guns, especially the AR-15 Bushmaster, a lot of kids would still be alive.
