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.
Currently, only 22 states submit any mental health records to the federal National Instant Criminal Background Check System.
Maybe 28 states have no crazy people. Would like to get a list of them.
