Trying to control knives is useless. A hand holds the knife and there's a mind behind the hand. If there had been no knives available, a screwdriver or any other tool could have been used. How to address the bigger problem is the 21st-century challenge. Loneliness leads to despair, and the more we possess the more empty we are. Perhaps politeness and social networking are two very different things. We mourn for the innocent victims and their grieving families.
