The two possible answers for the major questions
Answer #1. Not enough data to decide the question.
• Maybe no conspiracy and not enough evidence to point clearly away from conspiracy.
• Maybe a small conspiracy such as LHO and one or two others, and the others have remained quiet after he died.
• Maybe a huge, powerful conspiracy that could leave no trace of itself and keep everyone silent for 35 years. (The less evidence, the bigger and stronger the conspiracy.)
Answer #2. People are not thinking about the data correctly.
