A lot of times when a tragedy happens, people just say, "the person was mentally ill, lock them up". Instead of having that mentality, we should ask and investigate why that person commit that act. What caused that person to go mentally ill. If we can determine what is going on in the psyche of a person under mental health, we are able to prevent more tragedies. What good does it do to just lock them up and throwaway the key while not trying to figure out how they got to that awful state of mind.
