The guy was mentally ill. He had Schizophrenia and had a break with reality. It's not really a subject to joke about. This is no different than the African-American who the police shot last week whose parents called the police on, and when they arrived at the house the guy had a screwdriver in his hand and they shot him, because he walked out the parent's front door when they told him to stop. Both of these episodes are extremely sad and the police need to be better trained on how to stop people who are having schizophrenic breaks with reality. Several members in my family have schizophrenia and they literally have no idea what's happening to them when it overcomes them, they hear voices telling them to do crazy things, and they cease being themselves.
You should feel bad for this man. I don't think it's appropriate to make light of his situation when it cost him his life. Mental illness is a societal issue that spans all races, creeds, and religions. Have a heart will ya?
