If they know who Satoshi Nakamoto is why do they need to ask the US Department of Homeland Security to reveal it and they themselves should be able to provide accurate evidence of who Satoshi Nakamoto is. Many people want to know who the creator of bitcoin is but so far no one has been able to reveal it and this is like a conspiracy that is deliberately covered up.

What is the result of suing the US government if in the end they are also unable to reveal the name. This is not the first time this has happened because many people also intend to know who Satoshi Nakamoto is and in the end they still fail.
