Headers (not footers)

In my Comm160 class, we learned the secret to writing news headers. Some are born with the gift to seek out proper ommisible parts of the story, while others must learn what is necessary to include in a headline. I realized that if a reader could get all the information in the headlining story, why would one continue to read the full article? In my opinion, leaving the "who", also known as the "perpetrator", out of the headline, will keep people reading. We are quite the judgemental species, and often look for the perfect person to pass judgement (or give praise) to. Things like the date and time are perhaps not so important in local daily news.
