There isn't any circular logic: O'Keefe is a convicted criminal that has been successfully sued many times in relation to the videos he cuts and the unethical and libelous edits he makes to them. So, thus, we have no reason to believe the validity of these videos and every reason to believe he is using similar strategies. It is not reasonable people's fault that you cannot understand logic and common sense.
Okay, so he makes misleading cuts. Please explain to me how his recent videos could have been cut to make these completely innocent Democratic operatives look guilty.
Well, when he has been sued in the past and ordered to release the unedited tapes, it has become incredibly evident how he edited them to make them much worse than they actually were. I have every reason to believe that after this cycle is over and he is sued for libel by these people, a similar series of events will occur. If O'Keefe were willing to release the unedited tapes (he isn't), we could put this to bed. Until then, there is no reason for any reasonable person to believe that the edited tapes are accurate in any way.
