You're correct - the government can't take that responsibility away from 
the jury. What they're trying to do is limit the ability of the defense to 
explore the techniques used by law enforcement for both their accuracy and 
their acceptability in a modern society, as well as the truthfulness of the 
prosecution witnesses.

Imagine the OJ Simpson trial without cross-examination of prosecution 
witnesses about the evidence they found, the practices and procedures by 
which they found it, and the accuracy (or lack thereof) in the 
experimental/laboratory processes used to interpret it .. Mark Fuhrman 
would announce that he'd found a bloody glove, the crime lab would announce 
that blood on the glove matched the victims, end of story.

While the high-school civics theory of criminal trials is that jurors 
should begin the trial with minds full of reasonable doubt - in fact, were 
the prosecution to rest without calling a witness, every member of the jury 
would ideally be prepared to immediately vote "not guilty", for lack of any 
evidence in favor of guilt - it doesn't look like that in real life. As a 
practical matter, it's up to the defense to create reasonable doubt, and 
that's going to be a lot harder to do that if it's not possible to 
meaningfully discuss the process by which evidence was gathered.

How can limiting the availability of information to the defense and the 
jury do anything other than make trials less reliable?

One of the basic techniques of cross-examination, and of litigation in 
general, is to compare factual assertions made by the other side, either at 
different times or by different people (or both), find discrepancies, and 
look for explanations which would explain the discrepancies. People who are 
telling the truth should have stories which remain mostly consistent across 
time, and groups of people who all experienced the same series of events 
together should have stories which are roughly compatible.

Rules which allow one party to hide information make it more difficult or 
impossible for the other party to examine the hiddent information for 
discrepancies with other accounts or for logical and scientific 
implausibilities. That limitation makes it more difficult or impossible to 
make an argument to the jury that they should discredit the other party's 
testimony - either because the people themselves are untrustworthy, or 
because the methods they used were untrustworthy or unreliable.

Looking beyond the immediate "fair trials for defendants" issue, 
information hiding about law enforcement techniques is poor policy because 
it allows corruption to continue unchecked - see, for example, the 
unconstitutional wiretapping engaged in by the LAPD and the LA County DA's 
office revealed in late 1998 at 
<http://www.newtimesla.com/1998/081398/feature1-1.html> and discussed 
previously on cypherpunks. Oversight of police practices - by juries 
asserting their right to nullify, and by press reporting on revelations 
made at public trials - is essential to maintaining a minimum level of 
conformity with law by law enforcement.
