Writing for non-specialists

The people who act on a forensic report are rarely forensic examiners. A judge decides a case, a lawyer advises a client, a manager decides on disciplinary action, and in some countries a jury decides guilt. If they misunderstand the report, the quality of the examination does not matter. This lesson covers the readers of a report, plain-language techniques, a structure that puts answers first, a neutral tone and a review checklist. Giving evidence in person, including oral testimony and cross-examination, is covered by the IDFE Forensic Report and Expert Testimony (FRET) certification.

Who reads the report

One report must serve all of them. The answer is not to remove technical detail but to arrange it in layers, so that each reader finds what they need without wading through the rest.

Plain language

• Short sentences. One idea per sentence; split long sentences at "and", "which" and "because".
• Active voice. "I examined the laptop" is clearer than "the laptop was examined", and it shows who did the work.
• Define technical terms the first time, in the text or in a glossary, and spell out every acronym on first use.
• Explain once, then use the same term. If the report calls an item "the USB drive", it should not later become "the thumb drive" or "the removable media"; readers may think there are three devices.
• Write dates and times without ambiguity. "04/03/2026" means different dates in different countries; "4 March 2026" or "2026-03-04" does not. Always state the time zone.
• Use analogies with care. Saying that deleting a file is like removing a library's catalog card while the book stays on the shelf helps, but say where the comparison stops: the space can be reused at any time.

Structure: answers first

Busy readers read the first page. An executive summary at the start lists each question and gives a short answer, with the key limitations, in a page or less. The body then sets out the findings and interpretation, and the technical appendices hold the detail that specialists need. Every statement in the summary must match the conclusions and be traceable to the findings: the summary shortens the report, it does not change it.

Tables, timelines and figures

A timeline in a table, with one event per row, date and time, source item and a plain description, is often the clearest way to show what happened. Figures and screenshots help when they are labeled: each one needs a number, a caption, the item and location it came from, and a reference in the text that explains why it matters. A figure that the text never mentions should be removed. Screenshots of tool output should be cropped to the relevant records and must not be edited in any other way; if something is highlighted or redacted, the caption says so. Charts need labeled axes and units, and a scale that does not exaggerate small differences.

Neutral tone

Describe; do not argue. Avoid emotive words such as "suspicious", "obviously" or "tried to hide", and avoid statements about intent or guilt, which are for the court. Write "the suspect" or "the victim" only if that is the formal role; otherwise use the account name or the item number. Report exculpatory findings in the same plain, prominent way as inculpatory ones, and keep the same tone whoever instructed you. A useful test is to ask whether the report would read the same way if the other side had asked for it.

Jargon into plain language

Review checklist before signing

1. Every question is answered, in order, in both the summary and the conclusions.
2. Every conclusion can be traced to a finding, and every opinion states its basis.
3. Facts, inferences and opinions are worded so that the difference shows.
4. Limitations are stated where they affect a finding (Lesson 7.2).
5. Items carry IDs and hash values; tools carry exact versions.
6. Technical terms are defined, terms are used consistently, and times carry a time zone.
7. The tone is neutral, and no person is named where the data shows only an account.
8. A second examiner has reviewed the technical content, and ideally a non-specialist has read the summary.

A worked example: rewriting a paragraph

Before: "Analysis of the E01 revealed a $SI creation timestamp for report.docx predating its $FN creation timestamp in the MFT, indicative of timestomping by the subject." The sentence is accurate to a specialist, but it is unreadable for anyone else, and "by the subject" claims more than the data shows.

After: "I examined the copy of the laptop's drive (Item 1.1). The Windows file system, NTFS, keeps two sets of dates for each file. For the file report.docx, the creation date in the set that ordinary programs can change is earlier than the creation date in the set the system normally maintains itself. This pattern can be caused by software that changes file dates on purpose, but it also has ordinary causes, such as installers and archive tools that restore a file's original dates. On its own, it does not show who changed the dates or why."

The rewrite is longer, but every reader can now follow it, and the alternative explanation is visible rather than hidden.

Exam focus: Know who reads a forensic report and what each reader needs, and the plain-language techniques: short sentences, active voice, terms defined once and used consistently, acronyms spelled out, unambiguous dates with time zones, careful analogies. Expect questions on placing answers first in an executive summary that matches the conclusions, labeled figures and timelines, neutral tone without emotive words or legal conclusions, and the checks made before signing.
