I think everyone would agree the leaker should be more cautious, but The Intercept should also know best practices too around printed materials too.
If removing well-known, uniquely identifying printer microdots isn't a best practice, it should be.

Very true; where is the evidence that they did not do so?
You can read the search warrant at https://www.buzzfeed.com/stevenperlberg/a-federal-government..., which is more complete than the arrest warrant. Just read paragraphs 12-19, which cover the relevant probable cause. If the FBI don't know how it leaked (printed) and from where (Winner's home town), the case becomes extremely difficult. Instead, they had so much that she just confessed when they showed up.
