Don't threaten a reporter. You'll just make 'em ornery.
Example: When researching a fairly innocuous (I thought) story about a well-known organization, an interviewee asked to "edit" my story before it was published.
No. I explained that wasn't an option. I'll share facts for checking, but the only person who gets to edit my story would be … my editor.
Interviewee then "shared" a story about a previous magazine article about the organization, where someone was misquoted, and while he "didn't know the details," Legal got involved, and the magazine had to destroy all the copies, or pay money, or something.
Now I had to ask: If they resort to threats, what do these folks have to hide?
I dug deeper. The resulting story was a bit more negative than what I'd originally envisioned.
My original version would've been fair and accurate, as was the final result. There are many different ways to tell a story. The more negative version wasn't out of vengefulness. The threat pinged my reporter spidey sense, and that's where it took me.
But just know that, if you try to tell a reporter what to do, or worse, threaten, it is likely to backfire.
