Involuntary commitment is a legal process and gets reported to NICS. After the Cho/VT incident the feds pushed hard to get the states to send those records to the FBI.
Several states have yet to comply with the “reporting Standard”, particularly after reviewing the HIPAA rules. I don’t know if Florida is one of those declining. In deed we don’t know the nature, or extent of illness, or the treatment related to the gentleman’s condition. To make matters more complicated, the procedure for obtaining an order of involuntary commitment and the definitions of such commitments vary so widely as to make this title a joke.
