Throughout their research Williams and Weetman take note of the ever changing combinations of institutional structures, dynamic processes and agents in the routine usage of forensic science in policing. In order to make use of this

The current study seeks to clarify the role of CSI practices by looking further into trace and contamination avoidance. Along with trace and contamination avoidance, CSI work in general is studied in an effort to further the understanding of how it works between the field and in the courtroom.
