Sure he is. He's a counter-example to the claim that if you're innocent, you don't have anything to fear from the FBI. It's really not complicated, and the only thing offered in response is denialism.
Would you be suggesting that because of *an* instance of a wrongful charging/investigation/prosecution that *all* folk who are innocent must assume 'the man' is is out to get them and thus must lie? Are you saying that the *default* condition is to *not* have the conviction of one's innocence and the confidence in truth winning the day?
Among those under any significant investigation to the point of charging, I wonder what do the statistics say on the fraction who turn out to be innocent, and who turn out to have been wrongly dealt with? If most folk charged are (truly) guilty--of even some peripheral or unrelated crime that comes to light--then the argument for taking the default stance whereby the innocent must lie to protect themselves has a weak foundation.
If 'the man' is out to get you in spite of your innocence, then you're gonna be got whether you lie or not. What cost to tell the truth, which would only redound all the more to your character? Especially if and when the miscarriage of justice is redressed.
