Davi: Real time fact checking does not allow enough time to do an accurate job. Candidate might present facts or opinions on practically any subject and a moderator is not going to be educated enough to present unbiased rebuttal. In practice there is always some doubt about anything that is assumed to be a fact. Hillary is just trying to defuse the widely held opinion that she tries to miss-lead people about facts for her personal advantage. That is different than being wrong about opinions that a person thinks are facts. Both are problems but deceit is generally more dangerous than simple ignorance.
