Another thing to ponder, the boyfriend was detained on the day of the shooting (and I don’t suspect that the officers were cheery or believed him much when they stopped him) on the evidence that he (a)knew the victim, and (b)had a gun.
Some profile.
Yet an adult who was convicted of criminal insanity and prescribed psychoactive medications was left to his own authority.
Cho wasn’t “convicted of criminal insanity”
He merely went through some legal administrative hearings and after a bit of wrangling it was strongly recommended that he seek help.
There was no trial, no conviction, therefore nothing that could be legally entered into NCIS or any federal database.
Yes, in hindsight he should have been. But if he had been, he could have sued ‘them’ and very likely won.
Cho wasn't convicted of anything. He wasn't even institutionalized.
