Most people’s knowledge of the criminal justice system is founded on media portrayals of forensic investigations or court proceedings that are not always realistic. With this in mind, it is imperative that those who are living and breathing the criminal justice system provide as much guidance to the people who find themselves amidst legal cases, particularly the witnesses who may not necessarily have anything to do with cases directly but just know a thing or two that may shape its outcome.

This session’s instructors are Maricopa County Attorney Office’s Hilary Weinberg and Edward Paine. Hilary has worked at different bureaus with the Maricopa County Attorney Office since 1999. She was the Family Violence Bureau Chief between 2014-2019 and is most recently prosecuting homicide cases in the Vehicular Crimes Bureau. Meanwhile, Ed is a Deputy County Attorney since 2012 who has worked in the Vehicular Crimes Bureau for the majority of his career working on various cases from DUIs to murder.

Specifics of this course include:

  • The importance for those working in criminal justice to recognize misconceptions about the profession and how it can be very unfamiliar for other people.
  • The importance of witness preparation to ensure witnesses are not overwhelmed and are able to provide persuasive testimonies.
  • Pointers for lawyers who have to work with witnesses that highlight the usefulness of prep work, a third-party investigator during prep, telling the truth, and familiarizing with COVID-related court protocols.
  • Guidelines when working with different segments of the population as witnesses.
    • To be discerning in picking which law enforcement officer to testify in court taking into account their experience testifying, familiarity with the case, and impartiality.
    • Providing the information that the officer needs to know before testifying regarding the facts of the case, their conduct in court, the language they’ll use, and what to wear.
    • The importance of presenting the credentials and expertise of the scientists who’ll be asked to testify.
    • Leveraging the scientists’ expertise to better explain their testimony by illustrating/demonstrating findings and opinions in detail.
    • Strategies to get in touch with a doctor who will stand as a fact witness – how and where to serve their subpoena and coordinating court appearance with their schedules.
    • How common of a practice it is to have children as a witness and determining the need for the child to provide testimony.
    • Techniques to build rapport with kids and avoid traumatization of a child.
    • Modifications and accommodations to consider when working with kids in terms of verbal and comprehension ability.
    • Legal considerations for inmate witnesses including coordinating with their legal counsel, collaborating with the facility for transport and security concerns, and safety concerns for the inmate.
    • Clothing options when appearing in court and disclosing agreements made and benefits an inmate may get for testifying.
    • General recommendations for civilian witnesses including rehearsing direct and cross-examinations, attending to their questions and concerns, and providing them detailed instructions on logistics and appropriately dressing for court.
    • Dealing with recanting witnesses by utilizing records of their previous statements or 911 calls.
    • The importance of disclosing recantations and understanding potential underlying reasons for recanting.
