But they did mention the emails. You aren't making any sense.
You've claimed the only real evidence is the emails yet the emails are not evidence of anything. The articles you reference actually do mention the emails but regardless of what the articles mention there still isn't any evidence.
Try and be objective.
The Podesta emails were mentioned three times in the email - but none of them referenced the specific coded emails in question:
WHAT caught their attention? They don't say. Is that not a vital piece of information for readers?
The other references of the emails point out that Alefantis and Comet Pizza are mentioned in the emails as well. But they don't tie that string to the use of code words in the emails.
