Malcolm Barnstable is a gunman responsible for barging into the Coral Dragon restaurant and firing a warning shot with a demand of proof of child sex trafficking in the business. Barnstable was "self-investigating" over lies spread by fraudulent shock site owner Ron Duca and held everyone in the restaurant at gunpoint, demanding the lies be proven.
Barnstable was talked down by detectives, arrested, and charged with deadly weapon possession, criminal mischief, and menacing, according to a later press conference. (SVU: "Real Fake News")
