Handling and processing evidence
Handling and processing evidence is an integral component of crime scene management because it lays the foundation for everything the court must consider when weighing the admissibility of evidence. For the most part, the courts prefer testing being carried out in a laboratory setting. However, there are exceptions, such as times when an initial examination also yields valuable information.
In this assignment, you will differentiate between testing that might be done on-scene versus in the laboratory, identify testing that might be subject to preliminary testing, as well as compare the different results yielded by preliminary field versus laboratory testing. Support your assignment 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.
