The story of how 18-year-old Sarah Dawn McKinley shot and killed a man who authorities say was breaking into her house on Saturday has been getting lots of attention because of the 911 phone call she made and the already tragic circumstances surrounding the incident.

McKinley, of Blanchard, Okla., called 911 to say that a man was trying to get inside her mobile home and that she feared for her life and that of her 3-month-old son. She asked the 911 operator if she could shoot him if he got inside.

Several former rivals of Minnesota Rep. Michele Bachmann were quick to applaud the now-suspended campaign run by the only woman to have sought the 2012 Republican presidential nomination.

Jon Huntsman said Bachmann added an "energetic and passionate voice" to the campaign. Mitt Romney called Bachmann a friend with a "titanium spine." And Newt Gingrich extolled Bachmann's "considerable talent" and "great courage."

When the Pittsburgh Steelers start the NFL playoffs with a road game in Denver's Mile High Stadium Sunday, they'll do it without free safety Ryan Clark. That's because Clark, who has 100 tackles and the confidence of his coaches, also has sickle cell trait, which can cause severe complications at high altitudes.

The Food and Drug Administration is moving to stop the use of some antibiotics on animals. The agency wants to prevent overuse of these drugs so that bacteria don't develop resistance to them.

The announcement affects antibiotics called cephalosporins, drugs used widely to treat things like pneumonia or skin infections in people.

People without health insurance don't get enough preventive care — simple but important things like vaccinations and blood tests.

But surely having insurance every now and then is better than none at all, because people can get caught up on their tests when they are covered, right?

That's a widely held view, and one that would be good news to the millions of people who go on and off health insurance each year. Some of them are losing or changing jobs. Others slide on and off Medicaid as they take on temporary work, marry or divorce.
