Conspiration to kill the president. A single person cannot conspire, so that EX NIHILO a possible crime appears needing at least two people. Each of them alone may noy have a fourth ammendment interest BY HIMSELF (it is difficult to accuse someone of conspiration without a partner...) . A conspiarcy takes two to exist. It is not so easy as they state it. And it is because... people are mostly relations, not monads. It is not ex nihilo, it is ex essentia personae why the mutual interest may appear.

Edit: Imagine: we are searching your house looking for evidence of conspiracy. But you are the only suspect...WTF?
