Maybe, but you can't prove it from this incident.
On Saturday, police were called to Barnette's apartment by a panic alarm. When an officer arrived, police say, Barnette attacked him with a knife and a handgun.
Strange wording. I understand attacking with a knife. But what do they mean by 'attacked him with... a handgun?' Did she shoot at him or did she try to hit him with the gun? There is no mention of her shooting. Some clarification is required.
