This time, a terrible act of violence at an airport resulting in five deaths seems to have been perpetrated by a person who was mentally ill, perhaps schizophrenic:
[The shooter Esteban Santiago] visited the FBI’s Anchorage, Alaska, office a few months ago and told authorities that an intelligence agency was telling him to watch ISIS videos, according to law enforcement officials.
The officials said Santiago’s associates were concerned because he said he was hearing voices; they had accompanied him to the FBI office in Anchorage.
On Friday, Santiago flew into Florida on a Delta Air Lines flight from Alaska via Minnesota, officials said. He had declared his handgun in a firearms carrying case, law enforcement sources told CNN…
Santiago had purchased two handguns — a 9 mm Glock and a Glock .40-caliber — in the past, according to a law enforcement source with knowledge of the investigation. It is unknown whether either of these pistols were used in Friday’s attack.
Santiago’s criminal record in Alaska includes three offenses: having no proof of insurance in 2015, a taillight violation in 2015 and a criminal mischief charge, causing property damage of more than $50, in 2016…
The FBI looked into Santiago’s background and saw his military history but found no information to indicate radicalization, officials said. The FBI asked local police to take him to the hospital for a mental health evaluation. Santiago voluntarily checked himself in.

There doesn’t seem to have been much of a failure by authorities here, except the failure to predict human nature perfectly. Unless we are going to lock up every unstable person indefinitely, and search for and confiscate the weapons they already own, or ban flying with legal weapons legally stowed in the baggage area, or have an armed guard every few yards in all airports, I don’t see how this one could have been prevented.
In terms of concealed carry of weapons acting as a deterrent, an airport is obviously a zone where an assailant can be pretty sure that only law enforcement officials will be carrying. It’s a conundrum, and I don’t see a solution.
