Can you help me understand this Science question?

Crime scene management skills are an extremely important component of an investigation because evidence
that originates at the crime scene will provide a picture of events for the court to consider in its deliberations.
Locard’s exchange principle argues that during the commission of a crime, evidence transfer occurs between the
victim, suspect, and scene. In this paper, you will identify the key elements of crime scene management, the
function served by each, as well as repercussions of allowing a scene to become contaminated or not
establishing a solid chain of custody. Support your paper with examples from this week’s required material(s)
and/or a minimum of three other scholarly or credible resources and properly cite any references.
