First, there is an observation which is defined as information gained through some or all of the five senses. It can be qualitative, "there is a body in the car here on the back road " or quantitative, "there is a male body in a blue sedan, located on Green street one mile from the Watson bridge. From there, I can make an inference, about several possibilities including murder. For example, if I step outside my front door and the grass is wet, I can infer that it had rained, the sprinklers had been on, there was dew on the grass, or other reasons. An inference is a possibility based on information and prior background knowledge. But, it does not allow certainty without more information and context.
The reporter then went on to really add fluff to the story by interviewing a neighbor who did not see the car or the body, and had no valid information. "There are a lot of hunters around here and cars are always going too fast. This never happens around here". It would have been better for the reporter to have simply said that a car had been found with a body inside and we have no further information. Then tell me tomorrow what happened with certainty.
It seems that we have become familiar with, and comfortable living in a world filled with ambiguity. I believe that we could live as well with less, speculation, rumor, and guesswork. As Yogi Berra said "You can observe a lot by just watching".
