Minneapolis police, public officials and community members continue to search for answers following Sunday's shooting death of an apparantly mentally ill Somali man. Police shot the man after he allegedly refused to drop a machete and a crowbar he was carrying. Somalis in the south Minneapolis neighborhood where the shooting happened are angry at what they call excessive force used by the police. And mental health advocates say the shooting points out the shortcomings of the system that is supposed to help avoid such tragedies.
