Former federal prosecutor Ken White created a stir with his recent argument at Reason.com that neither President Donald Trump nor anyone else should voluntarily meet with investigators. By anyone else, White does not simply mean other people facing scrutiny in special counsel Robert Mueller’s probe. He means you and me. Ever.

According to White, the only reason prosecutors ever really want to interview targets is to trap them into a story and catch them in a lie. If they’re after you, you can’t talk your way out of trouble. Sure, you might have information that would exonerate you, but your lawyer can instead convey it informally to the investigators, without any risk.

White is right, but he doesn’t go far enough. Prosecutors want to catch you in a lie because, when they can’t prove an underlying crime, it’s often easy to prove that you lied to them. That’s where the problem arises. I’ve been telling my astonished law students for decades that except in certain well-defined circumstances, lying to investigators shouldn’t be a crime. And it shouldn’t. Period.

Part of the reason for my position involves symmetry. As long as government investigators are allowed to deceive you, you should be allowed to deceive government investigators. And deceive you they may -- rather willy-nilly. If a suspect confesses after police falsely tell him that his fingerprints were found at the crime scene, fine. If a suspect confesses after police falsely tell him that they have satellite images and DNA evidence linking him to the crime, fine. My view is that suspects should have the same freedom. If you can throw the police off the scent by telling them you weren’t there ... fine.

This last point is important. White argues that investigators rarely talk to suspects without strong evidence of their guilt. Again, you’re not likely to be able to talk them out of pursuing you. So if your lie changes the course of the investigation, the case must not have been that strong to begin with. Another reason not to criminalize the lie.

If, on the other hand, your lie doesn’t change the course of the investigation -- if they still come after you -- then the case was very strong from the beginning. And if the case is so strong that investigators still want to chase you after your lie, then your lie had no effect. So let’s force them to come after you for the crime they’re investigating, not for trying (and failing) to deceive them.

Remember, they can deceive you. When a lie by investigators leads to a confession, we congratulate them on their great police work. By that logic, if a lie by a suspect leads to a decision not to file charges, we should congratulate the suspect on great defense work.

Remember that the innocent as well as the guilty may lie, often to hide something that isn’t a crime but would be embarrassing or in some other way impose a significant cost. “I never met her” -- when in fact you’re having an extramarital affair. “I’ve never said a bad word about my boss” -- when in fact you’ve told friends how much you despise him. “I didn’t speak to him” -- when in fact you were the perfectly legal source on a story.

A lie is often our reflexive answer when we get into trouble. It can be automatic, even when what we’re hiding isn’t a crime. (And it’s often not.) This doesn’t make lies a moral good -- I’m on record that they’re almost always morally bad -- but that doesn’t mean we should punish the natural human instinct toward self-protection. We shouldn’t criminalize a reflex.

Yet we do. All the time. Prosecutors have a plethora of ways to charge a suspect with lying to them, even when they can’t prove any other offense. Of special prosecutors this is particularly true. I have been a critic of special prosecutors for going on 30 years now. A big part of the problem, as I have argued before in this space, is that they almost never prosecute the crime they were appointed to investigate. Instead, going all the way back to the administrations of Bill Clinton and George H.W. Bush, they prosecute people for lying.

Even in the Watergate investigation, the prosecutors had trouble discovering an underlying crime. But at least the famous March 1974 indictment that included President Richard Nixon as an unnamed “person to the grand jury known” charged more than making false statements and false declarations, the far-too-common offenses on which prosecutors rely. The indictment also charged conspiracy to obstruct justice and defraud federal agencies. Although the fraud charge was thin, the obstruction charge was strong -- and more than sufficient to bring Nixon down.

This is a distinction that matters. Obstruction of justice should certainly be a crime, as long as the overt act is more than simply telling a lie. If you and your buddies conspire over how to mislead investigators, that should remain illegal. So should destroying evidence. And many lies to the government should still be crimes: in particular, lies under oath, whether or not before a court or grand jury, or in documents signed under penalty of perjury. True, if prosecutors put suspects under oath before questioning them, the suspects will be more careful. But that’s the point: The formal trappings surrounding the statement will play an appropriate cautionary function. The person who is under oath will think about what to say much more carefully than the person who isn’t. That seems to me a good thing.

One might object that all of this would make the prosecutor’s job more difficult. But prosecution should be difficult, and should generally be aimed at discovering an actual crime. If, on the other hand, we aren’t going to grant suspects the right to lie to investigators, we should at least take away from investigators the right to lie to suspects.

One might further object that this approach would make it harder to get President Trump. I’m no Trump fan, but I don’t think that in the rush to bring him down, we should make it easier to get the rest of us.
