Bad analogy, unless your property is the King Ranch, and the car exploded at several thousand feet. Get a grip.
Get a grip? What does the location/altitude have to do with it? How is it ethical to withhold evidence? I resent the implication that I'm unreasonable for trying to insure that the investigators have the best possible chance to figure out why Columbia crashed. And I am puzzled as to why some of you are defending those who would inhibit such an investigation. I don't necessarily agree with the 1/4 million fine and lengthy prison time -- I merely say that it is unethical to knowingly keep evidence of an accident.
