Alternative Theories don't always include a conspiracy. A lot of times, the official story is still used as a base of reference. Extrapolations can be made from within & beyond the official base of the reports. Various patterns of coincidence or synchronicity might be discovered that aren't considered relevant to the official or conspiratorial account of things.

Thus, its good to take an expanded perspective of things, because sometimes one discovers data from various angles on many levels.
