Why is it important that everything in your report - preliminary or final - be as "letter perfect" correct as possible? In other words, what does it matter if a misplaced comma, sentence fragment, spelling error, or the like, crept in while you were writing and ends up on the client's (or the judge's) desk?
Our text emphasizes that in preparing your report, you should "describe what you actually found, not what you hoped to find." But the investigation has an overall purpose, doesn't it? Isn't that somewhat like "what you hope to find" or discover? Why or why not?
Why is explaining your data collection, analysis, and validation methods important? How should this be done? How does this relate to the chain of causality, or the chain of custody?
