I'm interested in how certain trials work in US Law, particularly when it comes to Character Witnesses.
How do defence teams go about selecting character witnesses, in particular when it comes to murder trials? For example, Carol Ann Boone being a character witness for Ted Bundy, she was surely biased and therefore should she not have been dismissed as a witness?
In this stream, does that mean that family members/friends/lovers are instantly ruled out when submitting character witness, due to ingrained biases?
Also, if chosen as a character witness what background would be required? For example, could someone impaired mentally be able to (through mental health conditions or addiction)?
Apologies if this has been answered already.
