What is more important: Watching the Cubs or not dying in a tornado?

Yesterday afternoon, there was a tornado warning for Cook County, which includes the city of Chicago. (Fortunately, we in Lake County only had severe thunderstorms and bushels of rain.) During the tornado, I was flipping between the local channels to see who had the best weather coverage, and I noticed something odd: WGN, which was showing an (away) Cubs game, didn't even put a tiny graphic or a scroll at the bottom of the screen indicating that 5.3 million people were in danger of a tornado. (Maybe 10 minutes after the warning had started, WGN finally did put up a graphic.) Is watching the Cubs on an unadulterated screen really more important than letting people know that a twister in descending upon their locale?
