Consider the two goals of data collection – maximizing the usefulness of the evidence and minimizing the cost of collecting it. Analyze why these goals can create significant challenges for an investigator. Determine what potential downfalls may arise in an investigation when limiting evidence collection operations purely based on cost. Examine the nuances of evidence collection when dealing with volatile and temporary data and provide an example. Suggest at least three procedures, tools, and / or techniques at the disposal of an investigator that could assist him / her in evidence collection of this potentially critical evidence.
