How it works

Three layers, always kept apart

CrimeHalo shows you what agencies published, makes it readable, and gives the people who live there somewhere to add context. Those are three different kinds of information, and CrimeHalo never blends them.

Layer 1

Official information

CrimeHalo collects publicly available incident information from government and police open-data sources, normalises it into one shape, and shows it on a map.

Every record keeps its own timestamps, its original agency wording, its case identifiers and its source. Where an agency approximates or withholds a location, CrimeHalo says so instead of guessing. A verified incident report and a dispatched call are different things, so they are counted and labelled separately and never added together.

Freshness is stated on every city: Live, Recent, Daily or Delayed. That is about the source, not about the city.

Layer 2

CrimeHalo Brief

A CrimeHalo Brief is a short, readable summary of a single incident, written only from the structured facts in that incident's source record.

It can phrase what the agency called the event, where and when it happened, the status, disposition or priority the agency recorded, and which official records are linked to it. It cannot add injuries, arrests, suspects, motive, blame or an outcome, because those are not in the record. When the record is thin, the Brief says so plainly rather than filling the gap.

If the source record changes, the Brief is written again from the new facts.

Layer 3

Community

Signed-in users can submit a short community report of something they observed, and can discuss any incident in its own thread.

Community reports are reviewed by a person before they appear, are shown with an approximate location, and always carry a community label. Discussion is user-generated and is never verified by an agency. How much an incident is discussed does not make it verified, important or ongoing.

Comments show only the display name a user chose. CrimeHalo never puts a legal name or an email address next to a comment.

What CrimeHalo can and cannot say

CrimeHalo republishes official records and rewrites them for readability. It does not investigate, does not establish new facts, and does not rate how safe anywhere is. Records can be revised or withdrawn by the agency later, and a report is not a finding of guilt. CrimeHalo is independent and is not endorsed by any police department or government agency.
