What you see in most conspiracy theories is that the real purpose of the theory is all about and based on proving an entity or agency (usually a U.S. Federal Government agency) is behind or involved in an event. The theory buffs are not really concerned about the event itself or what caused the event (proofed by the usual and predictable wild ramblings put forth). They consistently use the event itself as nothing more than a prop to ultimately keep their proverbial theory treadmill going (has to be caused by the U.S. government or aliens, usual examples). They like to offer theories on all kinds of events across many spectrum's as the process tends to consume them. They don’t just espouse one theory just like you don’t do just one potato chip. It’s always very easy to throw forth wild theories and rambling thoughts when you do not have to back them up with related knowledge, facts, science, and you have an overriding agenda to tie everything to a specific entity or government agency as the cause.
