I can not fathom the sense of overwhelming loss the citizens of the area must be feeling. Once in my life, I watched a small F1 tornado touch down about a mile from me. Thankfully, it wasn't bigger and didn't hit near anyone's homes or in the town I lived in. The sirens wouldn't have been much help as they only went off about half an hour AFTER we watched it.
It's really sad that the officer was killed while trying to help others. Just a couple of weeks ago, there were 2 tornadoes in Laporte County, Indiana and one in Berrien Springs, Michigan. An officer in Laporte was in her car, trying to get to shelter, and one of the tornadoes picked her car up and carried it several hundred feet across the road. The car was really a mess but she wasn't seriously injured. You just never know when it's going to be your time.
