You cannot possibly know that "without the redactions, both would be exposed for their dishonesty." The only possible way to know that is to know what the full, unredacted document says; which you don't.The DOJ and the magistrate are afraid of transparency. Without the redactions, both would be exposed for their dishonesty in allowing the unlawful search and seizure of Trump’s personal records.
You can easily assert dishonesty, but you cannot know the unredacted document will show dishonesty until the full, unredacted document is publicly available for all to see.
Regarding "afraid of transparency," the DOJ has been crystal clear stating its reasons for redacting the affidavit, and the magistrate agreed those reasons are valid. It's not about fear. Among other things, it's about the DOJ and magistrate's desire to maintain the safety of "a significant number of civilian witnesses."
That "significant number of civilian witnesses" statement surprised me. Previously, it had been suggested by commentators that a Trump or Mar-a-Lago mole told the DOJ exactly where to find the materials the FBI agents found when executing the search warrant. That led to a lot of speculation about who that mole could be. Now we see the unredacted portion of the affidavit talking about "a significant number of civilian witnesses."
Speaking figuratively, I imagine Trump's neck is getting tired as he continually looks over one shoulder and then the other.
