Police Report vs. Probable Cause Affidavit
By Christine Burke · Published 2026-06-01
The short answer
A police report is the officer's narrative of what happened; a probable cause affidavit is a sworn statement used to justify an arrest or charge. Because they are written for different purposes, comparing them can surface differences in emphasis, detail, or facts worth asking about.
What each document is for
The report documents events; the affidavit argues that there was legal cause to act.
Why compare them
Facts emphasized in one and absent from the other, or described differently, are worth flagging for review.
What differences may (and may not) mean
Differences are questions, not answers. Purpose and audience explain many of them; an attorney can assess significance.
