CASE GEOGRAPHY.

In Detroit, a case was never only an address. Streets, precinct lines, factories, rail corridors, the river and the distance between neighborhoods shaped how police moved through the city.

READ THE CITY BEFORE THE CASE

Six geographic forces shaped police work.

01 · STREET GRID

Arteries & side streets

Grand avenues moved traffic quickly; residential grids, alleys and commercial strips changed visibility, pursuit and access.

02 · PRECINCTS

Stations as anchors

A precinct was both a building and a territory. McGraw / Sixth Precinct anchors Ralph's earliest police geography.

03 · INDUSTRIAL CORRIDORS

Plants, yards & shifts

Factories and rail infrastructure generated their own rhythms of workers, freight, traffic and nighttime movement.

DETROIT WORKS →
04 · RIVER & BORDER

A city at an international edge

The Detroit River was transportation, industry and border geography at the same time.

05 · DOWNTOWN

Courts, headquarters & commerce

Downtown compressed police administration, courts, newspapers, business and transportation into a small area.

06 · EAST / WEST

Neighborhood scale

Detroit's size matters. A location on one side of the city could mean a very different street pattern, industry mix and police response.

Case Geography deliberately stops short of publishing a lookup-ready map of Book One investigations. The website explains Detroit; the book keeps the investigative story.

SOURCE STANDARD

Map the city. Protect the story.

Use documented public geography and historical context
Explain precincts, corridors, neighborhoods and transportation
Avoid publishing combinations of names, exact addresses and outcomes that reconstruct an unpublished case
Keep uncertain locations off the public map
