Of course you are only aware of those conspiracies that have been revealed.....the truly successful ones have not come to light yet.
Therefore your reasoning can only be based subset of all conspiracies.
The best place to hide something is:....in plain sight. And that's exactly what we have seen in this case....Merely changing the captioning of a photo can deceive the viewer..... The Back Yard Photo ( CE 133A) is a superb example..... That photo was displayed like giant FBI "wanted" poster on the cover of LIFE magazine in February of 1964. It was captioned ...
Lee Harvey Oswald with the guns he used to kill President Kennedy and officer J.D. Tippit. That BY photo was created to convey a lie....The photo depicted Lee Oswald as a heavily armed communist revolutionary.... But just as with a carnival gag photo which might show a person in jail the photo was a FAKE. Because Lee was actually a US government agent, who was attempting to deceive Castro's agents and lead them to believe that Lee Oswald was a true supporter of the revolution. If Lee Oswald had been successful in completing the hoax at General Walkers house in April of 63 the BY photo would have been published with the caption...

Lee Harvey Oswald with the guns he used to kill President Kennedy and officer J.D. Tippit. were duped into believing they were seeing a true photo of the assassin, because they had been bombarded with lies and false and confusing stories about the murder( it was always referred to the more acceptable "assassination") of President Kennedy. Some alert Americans knew that they were being fed a huge lie but were unable to make themselves heard above the US government approved tale, and when the LIFE magazine burst into the public view they threw up their hands, and cried "Fake".
And they were right, but not in the sense that some nefarious photo altering expert created the photo.....( in fact it is a very amateurish attempt to create a carnival fake) Some researchers tried to prove the BY photo was a fake that had been created to incriminate Lee Oswald. If they had merely changed the caption to the caption that would have accompanied the photo if Lee had been successful at Walker's in April.

There are a couple of aspects of the BY photo (CE 133A) that clearly show that the photo was "retouched" ( altered ). The most glaringly obvious is the addition of what appears to be a sling or carry strap to the photo. Apparently Lee added that carrying strap to make the rifle appear a bit more like a guerrilla's rifle....But it is so amateurish that it looks ridiculous..... and yet when most folks view the photo they don't see the obvious...It's hidden in plain sight.
