“Public” mass shooting vs not public. What makes a public mass shooting more significant for gun control (or anything else) than non public? It appears they found a subset that has gone up not an overall trend. If proponents of universal registration want to treat this as some kind of motivation actual events have not provided I’m not seeing it.

Even the author in conclusion demurs any increase in mental illness, but proposes nothing instead. The takeaway is not even the author knows what to do with the date except publish it.

I would propose that we have mental stressors from the great recession resonating out there. Availability of guns has been constant except those recent years of hoarding that made some guns hard to buy.
