What includes legality of arrest and witness names?

The correct choice involves understanding that case facts are the specific details that can be critical when assessing the legality of an arrest as well as identifying involved witnesses. Case facts encompass a wide range of information relevant to a particular investigation, including but not limited to the circumstances surrounding the arrest, any evidence collected, witness statements, and the behavior of the suspect.

These facts form the backbone of an investigation, laying the groundwork for understanding whether the arrest was conducted legally and appropriately. This provides a clear context for analyzing legal procedures and potentially supporting the prosecution or defense in a trial setting.

In contrast, the other options focus on different aspects of legal and investigatory work. Elements of a crime are the foundational components needed to establish that a crime has occurred but do not directly address the particulars of an arrest or witnesses. A summary of case factors may provide an overview but is typically not detailed enough to include individual witness names or the legality of an arrest. Investigation reports may contain relevant details, yet they can also vary in depth and scope depending on departmental policy and the case's stage, making case facts the most precise choice for detailing legality and witness involvement.
