[null and void]

The NICS system is good but if the government isn’t keeping their records up to date, they must do better.

The school district DELIBERATELY withheld any information from the local LEOs.

The LEOs made the DELIBERATE decision to do NOTHING on any of the 39 house calls they made.

The FBI NEGLIGENTLY failed to give local law enforcement a heads up. They couldn't find anything on someone posting that they were going to shoot up a school on an open forum under his own name? Is this abject incompetence, neglect or deliberate?

Exactly. There must be penalties for that. Harsh ones.
