In a New York Times article "A Trick To Snoop On E-mail" by Amy Harmon, she decides to discuss why emails are not as private as some of us might think them to be. She tells about a "watchdog group" that has discovered a trick people can use to bug an e-mail message and track the information you are sending to others. Amy Harmon is a national correspondent for the Times, covering the impact of science and technology on American life. She has won two Pulitzer Prizes.
In this article Harmon claims that there is an implant used in HTML e-mails that is not visible to the recipient and it enables the text sent in emails to be secretly returned to its original sender every time it is forwarded to another recipient, as long as the recipients' e-mail programs are set up to read JavaScript.
The author uses evidence to prove that she isn't just making her claims by quoting the chief technology officer for the privacy foundation (an educational and research organization) Richard M.Smith saying, "I looked at this and I said, `Whoa,' because it lets you spy on people, and it's so easy."This can also be considered a warrant seeing at to how she was sing his credibility to help support her essential claim.
Great analysis of claim and evidence. As you state, the warrant relates to Smith's credibility. In this case, the warrant seems to be an assumption that Harmon makes about the values of the audience - that they will accept Smith and/or the Privacy Foundation as a credible source.
