Well, he is a former US Assistant Attorney and now focuses on federal criminal defense, and is considered an expert, so arguments from incredulity don't exactly move the big dog.
An argument from authority has its pitfalls, but is not totally worthless. I was looking for something more empirical. But see below.
And it bears noting that he did link to backup, including but not limited to the Barry Bonds case, but our correspondent sees no back up....
I didn't check the Barry Bonds case, as it applies to only the link's author's points, which I'm happy to grant for the sake of argument.
But the other link, to the National Review article, is much better written. Here's the money quote:
Hence, federal agents interrogating people always ask some questions as to which they already have irrefutable proof, hoping that the target will lie and hand the feds an easy conviction.
What are the pros and cons of this practice?
The other issue, of course, is that this doesn't really apply to the case of Trump, in which case Trump has not been woken up and immediately interrogated (as in the anecdote at the beginning of the N.R. article). If ever there was a situation that would minimize if not reduce the likelihood of being manipulated into lying, it's Trump's. He had plenty of time, had professional advice at the highest level, and because Trump is working at the highest level (being the leader of the free world [gasp]), can be reasonably expected to function at the level, and so should be held to the standard of telling the actual, real, truth. For once.
ETA: remove, not reduce the likelihood of being manipulated
