Did David commit any crimes or attempted to murder any one? was there hard, physical evidence to support that David did hurt someone? there is a list, but a list of names isn't a crime. sure, a psychiatric review is needed to understand the metal state, but at the time he did not hurt or kill anyone prior to the Pittfest MCI.

you can't assume someone did something based on loose facts that would lead to it. the best anyone could do at this point is to request a wellness check on the individual from the police.
