Courts allow evidence about contemporaneous communications all the time.
Conspiracy
: the act of
conspiring together
Theory
: a hypothesis assumed for the sake of argument or investigation
Sorry my friend, your "reporting" of a hypothetical conspiracy theory (by definition) has no bearing in a court of law nor the decision of the jury. You are welcome to adhere to it as a means of justifying in your mind why the decision of the jury was "wrong" or "unfair". But the attempted rationalization has no bearing on what transpired in court.
