NOTE:was intending to post this in last thread but you know how that door closes...so bringing this over
Those witnesses will be questioned about what they SAW, who they spoke to and when, who else was there, and all kinds of questions about whether they discussed the content of their testimony with others and who those people were. The value of witness testimony is entirely dependent on their credibility. When credibility is lacking their testimony can be discounted.
Even at a GJ proceeding the DA has to present exculpatory evidence, including witness impeachment evidence. The DA can't just present witness testimony he/she knows is impeachable without disclosing that information. If an indictment does issue, I think a defense attorney would have a field day with the witness testimony here. And that's without knowing anything about the background of the witnesses, other than the criminal record of DJ which contains a conviction for an offense very relevant to character/propensity for telling the truth. There's also so much video and audio and taped interviews.
MO jury instructions are similar to those in other jurisdictions:
In deciding what the facts are, you may have to decide what testimony you believe and what testimony you do not believe. You may believe all of what a witness said, or only part of it, or none of it. In deciding what testimony of any witness to believe, consider the witness's intelligence, the opportunity the witness had to have seen or heard the things testified about, the witness's memory, any motives that witness may have for testifying a certain way, the manner of the witness while testifying, whether that witness said something different at an earlier time, the general reasonableness of the testimony, and the extent to which the testimony is consistent with other evidence that you believe.
The actual instructions may vary. Example from case upheld on appeal:
You are instructed that you are the sole judges of the credibility of the witnesses and of the weight and value to be given to their testimony. In determining such credibility and weight you will take into consideration the character of the witness, his or her demeanor on the stand, his or her interest, if any, in the result of the trial, his or her relation to or feeling toward the parties to the trial, the probability or improbability of his or her statements as well as all the other facts and circumstances given in evidence.

MO cases set out the proper standards and requirements for impeachment:
[During cross examination, a witness may be impeached at anytime by inquiring of the witness about any matter (even a collateral matter) involving (1) the witness's ability to perceive, (2) the witness's bias, (3) the witness's prior inconsistent statements, (4) the witness's prior convictions, or (5) evidence of the witness's character for truthfulness and veracity.
The ability to use extrinsic evidence to impeach (that is to say, documentary or testimonial evidence offered to combat a witness's denial of a matter during cross examination) varies depending on the method of impeachment employed. Parties are permitted to introduce extrinsic evidence to impeach a witness by showing his or her inability to perceive the events testified to; prior convictions; or to show bias, prejudice or interest in the proceeding, regardless of whether the subject of the extrinsic evidence is independently material to the case. Parties are permitted to introduce extrinsic evidence of a witness's prior inconsistent statement...

However, I also understand that at the time LE had bigger issues on their hands that they were dealing with.
