4.4 Complete Sentences, Avoiding Fragments/Run-ons & Concise Report Writing

The primary objective of official police report writing is to convey factual information clearly, concisely, and unambiguously. Reports serve as public records, investigative leads, and evidence exhibits in court. Structural flaws—such as sentence fragments, run-on sentences, or comma splices—distort narrative timeline and obscure responsibility. Furthermore, wordy or subjective prose undermines the professional credibility of the reporting officer. This section covers sentence structure completeness, active voice application, and concise factual reporting for the JCF examination.

Complete Sentences vs. Sentence Fragments

A complete sentence requires three structural elements:

1. A grammatical subject (who or what performs the action).
2. A predicate verb (what action is taken or state of being expressed).
3. A complete thought (it can stand alone as an independent clause).

A sentence fragment is an incomplete sentence construction lacking one or more of these required elements.

Common Types of Sentence Fragments in Reports

1. Dependent Clause Fragments: Introduced by subordinating conjunctions (although, because, since, after, while, when).
   • Fragment: Although the perimeter was established immediately.
   • Correction: Although the perimeter was established immediately, the suspect escaped through an unlit alleyway.
2. Participial Phrase Fragments: Starting with an -ing or -ed verb form without a main subject and verb.
   • Fragment: Searching the rear exterior of the commercial premises.
   • Correction: Constable Reid searched the rear exterior of the commercial premises.
3. Missing Subject Fragments: Omitting the actor responsible for the verb.
   • Fragment: Observed two males standing near the open door at 02:15 hours.
   • Correction: Corporal Sterling observed two males standing near the open door at 02:15 hours.

Run-On Sentences and Comma Splices

A run-on sentence occurs when two or more independent clauses are joined without adequate punctuation or conjunctions. A comma splice is a specific type of run-on error where two independent clauses are joined with only a comma.

• Run-On (Fused Sentence): The suspect fled the scene officers gave chase on foot.
• Comma Splice: The suspect fled the scene, officers gave chase on foot.

Both constructions violate English sentence boundaries and create confusing incident logs.

Three Methods to Correct Run-Ons and Comma Splices

1. Separate into Two Independent Sentences (Period + Capital Letter):
   • Correct: The suspect fled the scene. Officers gave chase on foot.
2. Use a Semicolon (For Closely Related Independent Clauses):
   • Correct: The suspect fled the scene; officers gave chase on foot.
3. Use a Comma and a Coordinating Conjunction (FANBOYS):
   • Correct: The suspect fled the scene, and officers gave chase on foot.

Active Voice vs. Passive Voice in Police Narratives

Sentence voice refers to the relationship between the subject and the verb action.

• Active Voice: The subject performs the action directly (Subject $\rightarrow$ Verb $\rightarrow$ Object).
  • Example: Constable Miller recovered the stolen firearm.
• Passive Voice: The subject receives the action (Object $\rightarrow$ Verb $\rightarrow$ Agent).
  • Example: The stolen firearm was recovered by Constable Miller.

Why Active Voice is Essential in Law Enforcement Writing

1. Establishes Accountability: Active voice clearly identifies who performed every action (e.g., who conducted the search, who seized the item, who made the arrest).
2. Improves Clarity and Brevity: Active sentences are shorter, more direct, and easier to follow.
3. Eliminates Unknown Actors: Passive voice often omits the actor entirely (The door was forced open), leaving courts to question who committed the action.

Acceptable Use of Passive Voice: Passive voice should only be used when the actor is genuinely unknown (e.g., The store window was broken prior to officer arrival).

Writing Concise, Objective, and Factual Reports

Police reports must record facts, not opinions, emotional adjectives, or wordy filler. An objective statement describes observable behavior and measurable evidence.

1. Eliminating Subjective Language

Replace emotional or speculative words with concrete factual descriptions.

• Subjective: The suspect was acting very suspiciously and looked angry.
• Objective/Factual: The suspect was pacing rapidly, clenching his fists, and shouting at bystanders.

2. Trimming Wordiness and Redundancies

Concise writing removes unnecessary phrases without losing essential detail.
