I wonder who said "always" wrong.

 Could you reference this?

 Again there is fraud, there are criminals, the issue with O'Keefe is having more wrong than right and the fact that he edits his content out of order and doesn't disclose this.

 He shows a question then plays a response from a different event.  If CNN did that in a Trump interview you would be pointing out that Trump wasn't responding to that question and saying we can't trust CNN, even if they expose the truth on some other issue.  But if O'Keefe does it all the sudden we are supposed to ignore the lies and just focus on the positives.

 If my neighbor lies to me all the time but then tells me the truth about who broke my windows and calls the cops leading to an arrest, I will still remember my neighbor lies to me all the time.
