Conspiracy theory
A conspiracy theory is a theory that is used in a case that is already solved to suggest that something devious had happened. It is usually used in a derogatory fashion, although in many cases it is used correctly to describe cover ups that were initiated by the government's secret service agency. Many conspiracy theories are in actual fact aspects of disinformation that are used by the same secret service agency to help with the cover up.
One conspiracy theory is that the government or aliens send out radio waves that are used for thought control. These can be defeated by wearing a hat made out of tin foil (aluminum foil).
An example of a conspiracy theory[edit]
A murder occurred, but it is not initially obvious who did it. Finally, after months of investigation, police conclude that someone did it, but the evidence simply doesn't add up. In court, suddenly lots of evidence is produced which nobody knew about previously, the existence of which appears to be an aspect of framing. The person who is arrested is convicted in court and the case is officially closed.
Various people then look at the evidence to suggest that in actual fact it doesn't mean what they say that it means. They then theorise a range of different scenarios which would lead to reasons why that country's secret service agency (or in some cases, other people with a vested interest in the case) would want to lie about it. In many cases, the conspiracy theory will claim that the government itself had committed the crime, giving a reason for it.
