The burden of proof

Mods if this is in the wrong forum feel free to move this topic.

Where dose the burden of proof lie concerning 9-11 ?
When a person is a accused of committing a crime the police have to provide evidence that the person is guilty. so people like me assume that people put forward 9-11 conspiracy's have supply the evidence to support there claim.

Now many people automatically support the US governments story but this overlooks the fact that the US government has to prove that there tale is true. In fact some people who set up to prove the US government story to be true end up joining those who question what happened.

It shouldn't be up to people to provide the burden of proof on behalf of the US government. In fact if people start by trying to prove the US governments story people seem to ask creditable questions and some of the more wild conspiracy theory's are avoided.

There are two sides to the coin and if a logical approach is taken the burden of proof seems to be working against the US government.
