If say there was an email from hilary saying that "The US would back X amount of billions in guaranteed loans to provide funding for infrastructure informer FARC controlled zones" one party now knows exactly how much to ask for, one party now knows a limit, one party now has more power... Or here is another example say on day 2 of the negotiations there would be some preliminary agreement on how many and what type of sentences would be commuted that's just one small point of the negotiation it hasn't been finalized but if leaked it can blow up the entire deal. FARC can say it's too little, the Colombian government/people can say it's too much, and all over something that haven't been finalized or agreed upon, on something that is likely to change 50 times over during the negotiations. You seem to think for some reason that leaking things prematurely isn't using you as pieces, it is you are a puppet of your emotions and feeding you specifically tuned information is effectively playing you like a string.
