The Boston Marathon is a high profile event, and when explosives are involved, the security response is elevated. Explosives != pillows. The "world renowned" aspect is just that. The world is watching how we respond to such incidents, and to attempt to marginalize this incident by comparing a mother smothering her children with pillows to bombs targeting a crowd is callous in the extreme. Of course we'd prefer to catch all criminals, especially those who target high profile events with explosives.
