Albert Einstein once said:

A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.

Experiments help us find the answers to problems.  Experiments help us find the Truth, or the closest thing to it.  Without experiments, the world so many of us take for granted today would not exist.

But what does this mean?  What is an experiment?  And why am I, an attorney, writing about it on a legal blog?

Defining Our Terms

Before getting to the “why,” let’s talk a little more about the “what.”

Science is made up of two basic activities: theory and experiment.  Theories try to say how the world is; experiments verify theories, and the subsequent technology can change the world. … From the time of the Scientific Revolution a sort of collective methodology has given free rein to three basic human interests: speculation, calculation, and experimentation.  (Paolo Rossi and Cynthia de Nardi Ipsen, The Birth of Modern Science (2001) Wiley-Blackwell, p. 183.)

Webster’s Third New International Dictionary (2002) defines “theory” variously as “a belief…a judgment, conception, proposition…formed by speculation or deduction or by abstraction and generalization from facts.”  A theory is “a working hypothesis.”  And a “hypothesis” is “a proposition tentatively assumed in order to draw out its logical or empirical consequences and so test its accord with facts that are known or may be determined.”

In short, a hypothesis is a guess and a theory is something not yet proven.

Theories come in varying strengths; that is, although a theory is always “theoretically” capable of being disproved, some theories are based on (or explain, or make sense of) so much evidence as to be considered true and only nutcases or fringe elements doubt them, while others are, as the definition suggests, “formed by speculation” so outrageous that only nutcases or fringe elements believe them.

How do we decide if a theory is believable, or doubtful?  The answer is with experiment, defined by Webster’s as “a test or trial…the process or practice of trying or testing.”

And now we arrive at Law.  The American legal system is “adversarial.”  Our “experiments” are performed in courtrooms, in front of witnesses.  (By that, I actually mean the jury and the public; not the witnesses who testify.)  The courts are where we test our hypotheses and theories concerning cases.

This system is premised on the well-tested principle that truth — as well as fairness — is ‘best discovered by powerful statements on both sides of the question.'”  (Commonwealth v. Rahim (Dock. #SJC-09031 Suffolk Co. Mass 2003) not paginated.)

Or, as the United States Supreme Court put it in 1975:

The very premise of our adversary system of criminal justice is that partisan advocacy on both sides of a case will best promote the ultimate objective that the guilty be convicted and the innocent go free. In a criminal trial, which is in the end basically a factfinding process, no aspect of such advocacy could be more important than the opportunity finally to marshal the evidence for each side before submission of the case to judgment.  (Herring v. New York (1975) 422 U.S. 853, 862 [95 S.Ct. 2550, 45 L.Ed.2d 593].)

So far so good.  But why did I feel the need to start this article by talking about scientific theories and experiments?  How does that relate to the practice of law and the administration of justice?

The Search for Truth

The answer is partly that the development of the modern legal system and modern science grew out of the same primordial soup.  Descartes, Bacon, Hume and a whole host of other philosophers were all concerned with developing a foundation and procedures for the ascertainment of Truth (with a capital “T”).

And Truth is exactly what we seek — or at least it is what we should seek — before making monumental decisions affecting the lives of other people. Because in Science the development of hypotheses, experimentation and the pursuit of theories may lead to the creation of new gadgets, greater production of food and, in short, may add to the lives of many; but in Law (at least the Criminal Law with which I’m concerned), we are taking away.

A person charged with a crime often loses their liberty, at least for a period of time.  The more serious the crime, the larger the portion of their life is lost.  In the most serious crimes, we may actually take away the remainder of a person’s life, by life imprisonment or even by killing them.

When we’re going to take away from someone’s life, we should be sure that we are not taking away from the life of an innocent person.

Until we complete a trial — and unfortunately, because we don’t always follow the foundational principles of our legal system, sometimes even after we complete a trial — we can’t really have confidence in this.  Sure, some people will feel confident that the right person was suspected, investigated, arrested, charged and convicted even without a trial that comports with our well-thought-out, historically-based and time-tested principles.  But then, some people believe you can tell the future by reading palms, consulting the Zodiac, or sacrificing chickens.

Several hundred years of experimentation have taught us that our system requires more.

The Hypothesis Shall Not Set You Free

There is a close tie between the ascertainment of Truth in Science and Law — when a crime has been committed, the police do a little bit of looking around.  At some point — usually fairly quickly — they come up with a hypothesis as to what happened and who is responsible.  They pass this information along to the District Attorney’s office.  Someone there looks at it and decides if the hypothesis seems reasonable.  If it does — and, sadly, sometimes even if it doesn’t — charges are filed.  Perhaps a deeper look is taken; a more-targeted investigation uncovers additional evidence to support the hypothesis.

Somewhere in this process, the hypothesis develops into a theory.  The prosecution prepares for trial where the hypothesis, they hope, will be proved.

But because we’ve had hundreds of years of experimenting with the best way to ascertain the Truth, we’ve come to understand that the adoption of a theory is a complicated and tricky thing.  Way back when we’re coming up with hypotheses, the process begins to develop problems.  Ever heard the saying, “When the only tool you have is a hammer, everything begins to look like a nail?”  The same concept applies in developing hypotheses and theories.  The police find a suspect.  They develop a hypothesis.  As it grows into a theory, the search for evidence to support the theory almost always turns into a search for evidence to support the original hypothesis.

We know that pursuing one particular theory can make it hard to find the Truth.  (Max Planck once remarked that “a new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.” (Thomas Kuhn, The Structure of Scientific Revolutions (1964) University of Chicago Press, p. 151.))  Pursuit of the Ptolemaic theory that the Universe rotated around the Earth lead to an incredibly complicated astronomical theory between the second through the sixteenth century.  Eventually, beginning about the sixteenth century, when the observations (evidence) became too difficult to fit into the theory, the Copernican Revolution — part of the Scientific Revolution — began to take over.

The desire to maintain belief in the original Ptolemaic theory was so strong (especially among Christians) that some people were put to death, burned at the stake.  Challenging treasured theories isn’t easy.  Arriving at the Truth sometimes comes at a heavy cost.

Ours is Meant to be an Adversarial System

What we should have learned by now — what our legal system purports to believe — is that the best way to find out the Truth is to have some people explore one theory and some people explore another.  Then we compare the theories to see which seems to better fit the facts, or evidence.

This is the best way to find the Truth in Science; it is the best way to find the Truth in Law.

Someone cue the defense attorney.

[T]he adversarial process protected by the Sixth Amendment requires that the accused have counsel acting in the role of an advocate. The right to the effective assistance of counsel is thus the right of the accused to require the prosecution’s case to survive the crucible of meaningful adversarial testing.  (United States v. Cronic (1984) 466 U.S. 648, 656 [104 S.Ct. 2039, 80 L.Ed.2d 657] (internal citations and internal quotations removed).)

I hear — often enough that I decided to write this article — people asking why I would want to be a defense attorney.  The reason is found in the second phrase of Einstein’s quote with which I started this article.

[N]o path leads from experiment to the birth of a theory.

By the time we get to the level of the experiment, we’re already working off of a particular hypothesis; we already have “a working theory.”  But it’s too easy for us to forget that if what we really seek is the Truth, then trying to disprove a theory is as important as trying to prove it.

And so our criminal justice system, which purportedly aims at finding the Truth, is based on an interesting idea:  Why not assign someone the job of trying to disprove the theory?

The Constitution of the United States, where it addresses criminal prosecutions, was meant to implement this idea.  Our Founders believed in it even more strongly we do.  As the United States Supreme Court noted in 1984:

When a true adversarial criminal trial has been conducted — even if defense counsel may have made demonstrable errors — the kind of testing envisioned by the Sixth Amendment has occurred.  (United States v. Cronic, supra, 466 U.S. at 656.)

Without good defense attorneys (and courts even-handedly enforcing the Law!), however, this cannot happen.  Instead, our trials become show trials, shams, kangaroo courts.

[I]f the process loses its character as a confrontation between adversaries, the constitutional guarantee is violated.  As Judge Wyzanski has written: “While a criminal trial is not a game in which the participants are expected to enter the ring with a near match in skills, neither is it a sacrifice of unarmed prisoners to gladiators.”  (United States v. Cronic, supra, 466 U.S. at 656.)

Why I Do What I Do

The reason I do what I do and the reason we need good defense attorneys is to ensure that we sacrifice neither the Truth, nor unarmed prisoners, to the State’s trained gladiators.

My hope is not that I “help put murderers and rapists back out on the streets,” but that because I do what I do — in the words of Chief Judge Irving R. Kaufman of the United States Court of Appeals for the Second Circuit — “justice will emerge from the forensic duel in the courtroom.”  (Irving R. Kaufman, “Does the Judge Have a Right to Qualified Counsel?” (May 1975) 61 A.B.A. J. 569, vol. 61, p. 570.  [How ironic that Judge Kaufman’s main claim to fame is the unjust sentencing of Julius and Ethel Rosenberg to death.])

Final Note

Not infrequently, people reading my articles, or talking to me, get the impression that I “hate” police officers, district attorneys and anyone who tries to take criminals off the streets.  This is not true.  I dislike dishonest officers and prosecutors who lie, distort the Truth, or hide evidence that would help arrive at the Truth, in order to convict my clients.  I don’t hate — or even dislike —the honest police officers and decent prosecutors who serve as necessary a purpose to the system as do I.

I believe in the adversarial system.  And remember that I said that the adversarial system requires able adversaries on both sides, pursuing different theories, and opposing one another.  But being “adversarial” does not require hating the other.  It doesn’t require underhandedness.  It doesn’t require refusing to turn over evidence as required by law.  It doesn’t even necessarily mean not cooperating with the other, when cooperation is appropriate.  (Fleshing this out will have to be left for another article.)

Ideally, I strive to meet Shakespeare’s description as presented in The Taming of the Shrew:

And do as adversaries do in law,
Strive mightily, but eat and drink as friends.

My job, our system of Justice, and the quest for the Truth in criminal cases requires me to be the best and most determined adversary I can be.  It doesn’t require me to “hate” anyone.

  1. Quite convincing and articulate. Couldn’t help thinking that I want you as my defense lawyer should I ever need one. Probably won’t be necessary now that Bush is out of office.
    Proud of ya nephew!

  3. Rick,

    Excellent article; this is a thorough explanation of the importance of competent defense, though I would have to agree with Mr. Kennedy’s remarks, above.

    I’d also take issue with your quote:

    “When we’re going to take away from someone’s life, we should be sure that we are not taking away from the life of an innocent person.”

    It seems it might be more appropriate to say:

    “When we’re going to take away from someone’s life, we should be sure that the person is guilty of the crime or crimes of which they are accused.”

    Just my $0.02.

  5. Interesting article, Rick.

    Having said that, however, I am not interested about the Truth of the matter before the court in the least. I’m only interested in disproving the state’s theory.
