And whose? This point is particularly important. Traditions of juridprudence vary from nation to nation.

In the US, which, as the scene of the crime, would be the venue of any trial (presuming a live suspect can be arrested and arraigned), the evidence has to be such that it convinces a judge either to issue a bench warrant or to accept an arrest as conducted by duly deputized officers of the court, usually police officers.

The suspect is remanded for trial and kept in custody or released on a reasonable bond. When flight risk is demonstrably high, the bond option is rejected.

At no time is the evidence required to be published for anyone except the officers of the court involved. Pre-publication of the evidence is considered prejudicial to the defense, and may result in dismissal because the jury pool is tainted.

In sensitive cases, judges have the legal option of sealing the records and restricting access to the information. Some testimony is heard in chambers, where only the judge, defense attorney and prosecutor hear it. Oh, and the accused, who must Constitutionally be allowed to hear the testimony against him.

In the case of a jury trial, the courtroom may be cleared at the discretion of the judge, so that the jury may hear the testimony without the public being present. Jury members are only allowed to discuss the particulars of the case, while it's going on, with each other. They may discuss the testimony after the trial concludes, but if the information has other significance -- if, for example, it is germaine to another case still under investigation -- they can be legally enjoined against discussing the case even after a verdict has been reached.

I guess the short answer is "no", the US has not broken any of its laws by not disclosing evidence to the public. It has, in fact, upheld the laws forbidding the discussion of cases under investigation. The only member of the public legally entitled to hear all the evidence is the accused, at his trial.

If Osama bin Laden wants to hear the evidence, all he has to do is turn himself in and go on trial in the US.
