People with an injury from Post Traumatic Stress don't hear voices or have psychotic delusions. PTSD had nothing to do with this. This man had schizophrenic and psychotic thoughts and visions. Don't imply that any mental illness means you are psychotic and will kill people. That's reckless and discourages people from seeking help for mental struggles. If he had PTSD, okay, but it had nothing to do with the reason he shot five people in the face two days ago.
