Theron Clark appeals from a judgment of conviction in the Eastern District of New York, following a jury trial before Judge Mark A. Costantino on two counts of an indictment charging that Clark knowingly and intentionally possessed, with intent to distribute (1) 211 grams of heroin, and (2) 18 grams of cocaine, both in violation of 21 U.S.C. § 841(a)(1) (1972). He was sentenced to two concurrent seven-year terms and an additional special parole term of three years, and is presently incarcerated at the Federal Penitentiary in Petersburg, Virginia. Because Clark and the public were excluded from the entire pretrial suppression hearing held to determine whether the drugs were lawfully seized from him as he was attempting to board an aircraft at LaGuardia Airport, we remand for another suppression hearing. And since the trial judge failed to give adequate and comprehensible instructions to the jury, we reverse the conviction and remand for a new trial.
This case arises in the context of a system of precautions taken by airline authorities and the Federal Aviation Administration to prevent the hijacking of commercial aircraft by identification of potential skyjackers through use of a “profile” screening method. See United States v. Bell,
If a “selectee” activates the magnetometer, he is informed of this and asked for his ticket and identification. If he produces satisfactory identification, he will normally be allowed to *243 board the aircraft, but if he cannot do so he will be “interviewed” by an airline representative or a marshal or both in an attempt to determine the source of the magnetometer’s reaction. Failing a satisfactory explanation, the “selectee” will be asked to submit to a patdown of his person and, if necessary, to a search of any articles he may be carrying, in order to determine whether whatever object activated the magnetometer presents a danger to the other passengers and crew members boarding the flight. It does not appear whether he is advised that he has a right to refuse to submit to the search if he decides not to board the plane. Nor is it clear that if he refuses to allow himself or his baggage to be searched, he will simply be turned away without a search and not be allowed to board the plane. If a marshal observes a bulge in his outer clothing which the marshal reasonably suspects may be a weapon, the marshal apparently conducts a protective frisk of the “selectee” anyway.
In the present case, a Deputy United States Marshal, Vincent LaRosa, searched a small handbag carried by appellant as he was proceeding to board a plane bound for Raleigh, North Carolina, and seized from within it the illicit drugs which formed the basis for appellant’s prosecution and subsequent conviction. Clark moved to suppress the drugs as the product of an unconstitutional search, and a pretrial hearing was held on the motion.
The Suppression Hearing
At the commencement of the suppression hearing appellant was not present. The government made a formal motion, at the instance of the court, that Clark be excluded from the proceedings and that the hearing be conducted in camera “to insure that the [hijacker] profile will remain secret in order to deal with potential skyjackers.” The motion, to which defense counsel voiced no objection, was granted. Clark and the public were excluded from the entire suppression hearing, though appellant was represented throughout the course of the hearing by counsel.
Only two witnesses, Marshal LaRosa and an Eastern Airlines Supervisor, Brian O’Neil, testified at the hearing. Except for a very brief description of the “profile” criteria by Mr. O’Neil, the testimony given in the defendant’s absence was wholly concerned with the circumstances leading up to and following the seizure of the drugs. In essence, the witnesses testified that they had been alerted that a passenger on the flight to Raleigh had been designated a “selectee.” When Clark appeared at the boarding gate for that flight bearing the distinctively marked boarding pass which identified him as a selectee, O’Neil asked him for it, ascertained that the ticket inside also indicated appellant was a selectee, and verified himself that Clark met the profile criteria. After Clark passed through the magnetometer and activated it, indicating the presence of metal, O’Neil introduced himself and Marshal LaRosa and requested identification. The testimony at the suppression hearing (at which Clark did not testify) indicated without dispute that Clark did not present any identification, 2 and LaRosa consequently asked Clark if he would submit to a pat-down, to which appellant reportedly replied, “Go ahead.” 3 Finding nothing *244 which would have activated the magnetometer as a result of the frisk, LaRosa told Clark to open the locked bag he was carrying. Clark complied and LaRosa searched the bag looking for weapons. Noticing a bulky object wrapped in a towel, he unwrapped it and uncovered a box which he opened with the thought that it might contain explosives. Instead, the box was found to contain substances which later testing showed to be heroin and cocaine. The handbag also contained a medallion, a tie clip, and a can of shoe polish which would have triggered the magnetometer.
It is readily apparent and not surprising that the suppression hearing covered a wide range of testimony besides the profile criteria in order to determine the validity of the search. At the conclusion of the in camera hearing, the district court found that “the method in which defendant was stopped and frisked was reasonable under the circumstances and in accordance with the profile that has been established a reasonable search was conducted and the finding of the contents should not be suppressed.” What was surprising and wholly improper was the exclusion of the appellant and the public from the course of an entire pretrial proceeding designed to determine, from evidence of events in which the appellant participated, whether his constitutional right to be free from an unreasonable search and seizure was violated.
In United States v. Bell,
The case now before us presents a wholly different set of circumstances. The government frankly concedes that “there was testimony adduced from its two witnesses at this in camera suppression hearing which did not require the protection from disclosure that their testimony concerning the profile required and, in addition, that had appellant been present in court during the testimony of these witnesses he might conceivably have been able to assist defense counsel in her cross-examination of these witnesses.” 4 And indeed there was an abundance of testimony concerning such non-secret matters. The 45-page transcript of the testimony of Marshal La-Rosa and of Eastern Airlines Supervisor O’Neil reveals that O’Neil’s testimony regarding the characteristics of the FAA profile was limited to a few sentences and that LaRosa was not questioned at all on the subject. For the most part the testimony of these two witnesses was concerned with the circumstances surrounding Clark’s activation of the magnetometer, the interrogation and frisking of him, the search of his bag which led to the discovery of the drugs, and his arrest. This proof bore directly on such questions as whether Clark produced identification before the search of his bag (if he had done so he apparently would have been permitted to board without being searched), and whether he voluntarily and intelligently consented to the search of his bag, in which the narcotics were found.
Without having the benefit of Clark’s presence at her elbow to point out potential inaccuracies in the testimony of the two witnesses and to furnish factual information for' use in cross-examining them, Clark’s counsel was handicapped. Moreover, while we do not know what the record would have revealed if a proper suppression hearing had been held, testimony given later at trial indicated that she may have been unaware of facts that could conceivably have led a court to conclude that the search of Clark’s bag was unlawful. At trial, for instance, it was brought out that La-Rosa, who testified that Clark did not identify himself prior to the search of his bag, had testified before the grand jury that prior to the search Clark had produced a driver’s license at the loading ramp in response to O’Neil’s request for identification. Clark also testified at trial that he had earlier given the ticket agent his driver’s license. See notes 2 and 3 supra. Furthermore, Clark testified that at the time of his arrest he was 21 years old, he had been an addict since he was 15 or 16 years of age, and he was under the influence of drugs, from which he was beginning to suffer withdrawal.
The government makes a valiant but vain effort to save the hearing by suggesting that references to the operation of the antihijacking program were made throughout the hearing and that the risk of an inadvertent disclosure of the profile criteria in appellant’s presence was sufficient to justify the broad exclusion ordered by the trial judge in this case. Moreover, it suggests that even if the wholesale exclusion was error it was harmless because the same testimony was given at trial when appellant was present, and that any error was waived because appellant’s counsel indicated prior to her cross-examination of O’Neil at the suppression hearing that it was not “going to be necessary for me to speak to my client.”
We cannot treat the matter of appellant’s constitutional right of confrontation so cavalierly. The exclusion of the defendant permitted in
Bell, supra, was a
carefully limited one. It rep
*246
resented an exception to the general right of a defendant “to be present at a suppression hearing where testimony is to be taken, see 8A J. Moore, Federal Practice ¶ 43.03 [1] (2d ed. 1969); 3 C. Wright, Federal Practice & Procedure § 721 (2d ed. 1968),” United States v. Dalli,
The Sixth Amendment’s guarantee that “[i]n all criminal prosecutions, the accused shall enjoy the right . to be confronted with the witnesses against him” has been held so fundamental as to be applicable to the states by the Fourteenth Amendment. Pointer v. Texas,
Barring the public from the entire hearing was likewise an error of constitutional magnitude. Without the justification of “protection of the air travelling public,” or other compelling reasons, see United States v. Bell,
supra
464 at 670, there was no reason to deprive the accused of
his
right to a public trial, see Estes v. Texas,
We are wholly unpersuaded by the government’s suggestion that appellant’s inability to confront the witnesses at the suppression hearing and to assist his counsel in his defense was harmless error. In
Bell
the search of the defendant’s person leading to discovery of “hard objects” in his raincoat pockets which could have been gunpowder or explosives used by a hijacker on the plane but turned out to be narcotics was justified because (1) he met the criteria of the hijacker profile, (2) he activated the magnetometer, (3) he had no personal identification, and
(4)
he volunteered that he “had just been released from the Tombs and that he was out on bail for attempted murder and narcotics charges,”
Nor is the government helped by the fact that Clark had an opportunity later at trial to confront and cross-examine the witnesses who had testified at the suppression hearing. Manifestly the trial focuses on the issue of guilt or innocence, while the suppression hearing centers upon the validity of the search for and seizure of evidence which the government plans to use later in seeking to prove guilt. The defendant's participation in his defense may take different forms at each stage. Cf. Simmons v. United States,
Equally unconvincing is the suggestion that appellant waived his Sixth Amendment rights when his counsel told the district judge that it would not be necessary for her to speak to her client prior to her cross-examination of O’Neil. Even if counsel intended to waive appellant’s presence at the hearing, which we doubt, by making that statement and failing to object to his exclusion,

could certainly not be said to have amounted to “an intentional relinquishment or abandonment of a known right,” Johnson v. Zerbst,
Under the circumstances the exclusion of the defendant and of the public from that portion of the suppression hearing which did not deal directly with the characteristics of the secret antihijacking “profile” constituted plain error. Rule 52(b), F.R.Cr.P.
The Trial Judge’s Instructions to the Jury
We turn to the trial judge’s instructions regarding the legal principles which the jury was required to apply in determining whether Clark should be convicted or acquitted of the two charges against him. If justice is to be done in accordance with the rule of law, it is of paramount importance that the court’s instructions be clear, accurate, complete and comprehensible, particularly with respect to the essential elements of the alleged crime that must be proved by the government beyond a reasonable doubt, see Holland v. United States,
The indictment contains two counts, each of which charged appellant with a violation of 21 U.S.C. § 841(a)(1) (1972) 7 based on his alleged knowing and intentional possession of narcotic drug controlled substances (Count I, heroin; Count II, cocaine) with the intent to distribute them.
At the beginning of his charge, and long before he read or described the contents of the indictment and relevant statutes, the trial judge launched into an abortive and confusing description of the two elements of each alleged offense.
8
“Knowledge” and “intent” were differentiated at first and then confusingly lumped together without explanation and without any attempt to define in a meaningful manner what must be proved to establish the two distinct and crucial elements of each alleged offense. Although the court referred to the necessity of proving “specific intent,” that term, which presumably referred to the intent to distribute the narcotics, was never defined, though it was later stated to be an essential element of the alleged crime. Absent clarification this would have required a new trial, since the effect was almost surely to confuse or to leave an erroneous impression in the minds of the jury. See
*249
United States v. Gillilan,
The government’s effort to minimize the effect of the error by suggesting that the defendant’s entire defense was “lack of knowledge of the contents of the suitcase,” 11 is insufficient to shoulder its appointed burden. Whatever defense appellant chose to stress for his part, the government retained the burden of proof beyond a reasonable doubt of each element of the offense, including intent to distribute narcotics. Moreover, that burden had to be met on the basis of proper instructions.
Further errors appear in other portions of the court’s charge. Circumstantial evidence was vaguely defined as evidence that
“would indicate”
proof of such essential elements- as guilty knowledge and intent.
12
Despite references elsewhere in the charge to the government’s burden of establishing guilt ac
*250
cording to the reasonable doubt standard, the jury was not entitled to infer proof of guilty knowledge and intent merely on the basis that circumstantial evidence
“would indicate”
such crucial elements. See United States v. Fields,
The trial judge’s instruction on inferences not only failed to define what an inference is, see, e. g., Mathes, Jury Instructions and Forms for Federal Criminal Cases,
We must regretfully conclude that, despite the surprising absence of objection by appellant’s counsel, the trial judge’s charge, viewed as a whole, is so deficient and defective in material respects as to amount to “plain error affecting substantial rights” within the meaning of Rule 52(b), F.R.Cr.P., United States v. Fields,
supra.
The error is one that we feel bound to consider on appeal not only to assure appellant of a fair trial but to protect the integrity of our administration of the criminal justice system, see United States v. Vaughan,
We recognize that the task of delivering an accurate and truely instructive charge to a jury is a demanding one. Of foremost importance is the necessity for organizing and outlining governing legal principles in a logical sequence that will fairly inform the jurors of the essential rules to be applied by them in reaching their verdict. Certain principles, of course, are of such a standard and recurring nature that they should present no serious problem for the court in the average case. Others require more preparation and thought on the judge’s part. Complex legalisms must be translated into simple prose that will be understandable by the average layman. The essential elements of the alleged crime or crimes and of any defenses raised by the defendant should be clearly described. Terms of legal significance should be defined in a way that will be understood. If illustrations are to be given, and they are often instruc *251 tive, they should be furnished in addition to, not in substitution for, plain explanations of those criteria that are to govern the jury’s deliberations. In a factually complicated or protracted case, where the jury may have difficulty recalling the evidence, the judge may find it advisable to marshal the parties' contentions and proof. A nice balance must be struck between brevity and verbosity. A clear delivery in a tone that will command and retain the jury’s attention can be of considerable aid to the jury in understanding the legal principles by which it is to be governed.
A few gifted jurists, aided by extensive experience on the bench, are capable of extemporaneously delivering instructions to the jury which meet these demanding standards, at least in cases where the issues are relatively simple or recurring and the governing principles well established. But most trial judges, particularly those of limited experience, find it advisable to prepare in advance at least a rough written outline, if not a fully developed text, of the instructions to be given to the jury. Although additional time and effort is required in this process, it insures a logical and orderly organization and the avoidance of error. We are persuaded that if that procedure had been followed in the present case most if not all of the errors could have been avoided.
The Supreme Court observed in Bollenbach v. United States,
Reversed and remanded.
Notes
. The system has recently been changed. Under new FAA airport security regulations, airport operators are required to provide facilities and procedures “to prevent or deter persons and vehicles from unauthorized access to air operations areas,” and must prepare and submit a written master security plan which must be approved by the Administrator, 14 O.F.R. § 107.3 (1973), and then implemented, § 107.7. The plan must now provide for the continuous presence of a law enforcement officer “at the point of, and prior to and throughout, the final passenger screening process prior to boarding, for each flight. . . . ” § 107.4. It appears that the passenger screening process presently in use includes a search of the “carry-on” baggage, of all passengers who may, in addition to passing through the magnetometer, be asked to disclose objects on their person which have activated it. .
. At trial, however, Clark took the stand and testified that he produced his driver’s license when first asked for identification. At the suppression hearing and at trial, Marshal LaRosa testified that the license was not presented until appellant was interviewed in the Marshal’s office after the narcotics had been seized. Upon cross-examination at the trial, however, it appeared that LaRosa had told the grand jury that appellant “came up with an expired operator’s license” when first asked for identification. He explained the discrepancy by stating the grand jury testimony was incorrect.
. LaRosa, however, observed at the suppression hearing that when O’Neil asked appellant for identification, appellant “seemed to be in a fog.” At trial, he ob *244 served that appellant “appeared to be stupefied. He didn’t know if he was going or coming.” Appellant testified at trial that he had “shot up some dope” prior to his unsuccessful attempt to board the flight to Raleigh. He did not testify at the suppression hearing, however, and his physical condition at the time of the search was not explored.
. Appellee’s Brief 9.
. While we took some comfort in Bell from the fact that the exclusion there was from the suppression hearing and not from the trial, that was only in the context of a necessary, limited exclusion from testimony of uncontested facts and not, as here, in the context of a total exclusion from all the testimony, some of which might have been controverted, see notes 2 and 3 supra, concerning the search and seizure.
. Under the circumstances an objection may have appeared to her to be futile, as would effective consultation with her client in the midst of the hearing, cf. United States ex rel. Negron v. New York,
. That section provides:
“§ 841. Prohibited acts A — Unlawful acts
“(a) Except as authorized by this sub-chapter, it shall be unlawful for any person knowingly or intentionally—
(1) to manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or dispense, a controlled substance;....”
. “And each count, of course, in order to convict this defendant, and I’ll give you the rule of reasonable doubt a little later on in my charge.
“Each count must be proven to your satisfaction to the principle beyond a reasonable doubt and involves two elements : One is a question of knowledge and the second a question of intent, and I’ll tell you first what knowingly to do an act means or have a knowledge of it, or what intent means.
“An act is done knowingly, done voluntarily and intentionally, not because of mistake or extent or other reasons. As I’ve said to you, the specific intent in this case must be proven beyond a reasonable doubt, otherwise it cannot be a conviction.”
. “To constitute the crime charged in the indictment, there must be the joint operation of two essential elements; an act forbidden by law and an act in an attempt to do that act.
“Before a defendant may be found guilty of a crime, the prosecution must establish beyond a reasonable doubt that under the statute described in which I’ll read to you a little later on in these instructions, defendant was forbidden to do the act number one, and the charge in the indictment, and number two, that he’s intentionally admitted the act as stated before.”
. “[A]nd if you notice, I gave you the definition of knowingly and intentionally and you must now find, if you are going to convict this defendant under that section, you must find those two elements that I have described to you, knowingly and intentionally, was going to violate this law that I have read to you, including the next section, 841 (a) 1 which reads as follows: ....
“As I’ve said to you, both of these sections require two elements to be proven by the Government in this case; one is that the act of knowingly, intentionally possessing a controlled substance and the second, the intent to distribute it, and I’ve told you what they were, and these two items and these two essential elements must be proven by the Government by the principle of a reasonable doubt as to each essential element.”
. Appellee’s Brief 12.
. “Now, circumstantial evidence is that evidence is not directly proven to you. For instance, direct evidence would be like the suitcase, and the items of the suitcase, that’s direct evidence, that’s something they have knowledge of and you can see circumstantial evidence is that evidence that surrounds, and because of the inability to have evidence that would tend to be relative to it, it comes in circumstantially.
“You may consider both types of evidence ; circumstantial evidence would be, for instance, whether or not all of the evidence taken together would indicate whether or not this defendant had knowledge or intent or both to commit this crime to which he’s been charged.”
. “At this point, the Court would like to tell you you can also draw inferences from a material fact in the case.
“Now, a material fact in the case would be the bag, and the contents of that bag. You may draw an inference from that material fact, but only one inference that you may draw.
“To give you an example, if I had a glass of water on my bench and I tip it over, you can drawn an inference the water will fall to the floor. If I tip over the same glass of water, you cannot draw an inference that it will be caught in another glass on the floor, so you can only draw one inference in a material fact in a case. Any material fact in a case and any fact that you think you can deduce and draw an inference.”
. “Sometimes one statement from the person, you look at the person and they said something to you, and you may have been with your friends. ¡Somehow or other you don’t either like that person or you don’t believe what they told you. That’s your good common sense working.” (Emphasis supplied)
. Because the conviction is reversed, we need not consider appellant’s contention that errors were committed in the sentencing proceeding. We do note, however, that a district judge is obligated to exercise his discretion as to treatment or imprisonment under the Narcotics Addict Rehabilitation Act, 18 U.S.C. § 4251 et seq., for eligible defendants.
