Are you being ironic deliberately?
You criticise people for supposedly making assumptions yet you assume that Patti assumes a 50/50 possibility either way. Where does Patti claim that it is a 50/50 chance? Are you just assuming that she does because you have no real examples of Patti's assumptions?
You also assume that Patti has not evaluated the evidence, based only on the fact that she disagrees with your own assumptions.
The assumption that the phone call was possible is reasonable and a long winded biased diatribe from scipio does not change anything.
I am not making any assumptions Patti stated the following:
Unfortunately I am not as tunneled as you when there could be an alternative Skip. My eyes are wide open, if fact they go beyond wide they are vastly open. 
...
Its my opinion that no phone call can be proved one way or the other and to say it did or it did not happen is stalemate, for its unsafe to categorically say one way or the other. On the other hand its a case of what you and I believe.
Evidence speaks, assumptions go no where.
I didn't make any assumptions, Patti was crystal clear.
Patti has never dealt with the issues I raised which establish the call was not reasonably likely to have occurred. Nor has any other Jeremy supporter despite being challenged to do so time and again.
Patti chooses to ignore such and just pretend there is no evidence that tells us whether the call happened or didn't and thus there is reasonable doubt over his guilt. It amounts to creating the fiction the call was possible to create the fiction there is reasonable doubt.
