Little side bar just because something is a conspiracy theory doesn't mean it is 100% false.
Look at the Las Vegas Shooting. FBI basically said we don't know what the *** happened. And they are a large government agency. That leads a lot of people to believe there is a conspiracy about the "alleged shooter".
Jeffery Epstien murder etc. When you don't get much information on a controversial thing. People tend to make a conspiracy theory to fill in the gaps.
