I just saw the witness examination of the George Floyd case. The 18 year old female witness went on to ramble about how she felt so sorry for Floyd and that her father and brothers are all black just like Floyd.
Any reasonable person would agree that she is prejudiced and biased.
So then, what is the theory that justifies allowing prejudiced and biased witnesses to testify?
After all, prejudiced and biased citizens are not allow to serve as jurors.
