Presumably the police and the Waterbury state's attorneys office, treated the patron a little nicer that "seized the patron's handgun," as reported by the fifth-column NBC-Connecticut 'reporter.'
Otherwise, the patron should be cooperating with the police through and with the advice of his lawyer.
I hope the first words out of the patron’s mouth when the cops showed up were “I was in fear for my life and now I am traumitized and I need to talk to my lawyer.”
