About the research
How these films
are researched
Badges & Chrome tells the history of American police vehicles — the machines, the departments, and the decisions behind them. This page explains where the information comes from, how it’s checked, and what happens when we get it wrong.

What this is
Badges & Chrome is a documentary channel and archive covering the history of American police cars, motorcycles, and the law-enforcement machines that shaped them — roughly 1899 to 1978.
It exists because this history is genuinely under-documented. The police car is the most familiar machine in American life and one of the least examined. Manufacturers’ records are patchy, department archives are scattered, and a great deal of what circulates online is repetition rather than research. Where a fact is well established, we state it plainly. Where it isn’t, we say that too.
How a film gets made
01
Research first
Before a script is written, the core claims are checked against published automotive history, period magazines and department publications, marque-club archives, museum records, and primary sources where they exist.
02
Write, then verify again
Once drafted, each script goes through a second pass in which every number, date, and named person is re-checked. Claims that don’t hold up are removed or hedged — not softened quietly, but explicitly marked as uncertain.
03
Hedge honestly
Where accounts conflict, the script says so. You’ll hear phrases like “usually traced to”, “reportedly”, and “according to lore” — these are deliberate. They mark the boundary between what is documented and what is repeated.
04
Cite on the page
Every video has a page on this site listing the sources behind it. If a claim on this site isn’t sourced, it shouldn’t be there.
What we’re careful about
A few areas come up repeatedly, and they’re worth naming.
Where we’re careful
Production numbers
Factory records from the 1930s to the 1970s are frequently incomplete or contradictory. Where sources disagree, we give the range and say which figure is documented rather than picking the most impressive one.
“Firsts”
Claims that something was the first police car, the first radio car, or the first police package are often disputed, and the answer usually depends on definitions. We say “among the first” or “usually credited to” unless the record is genuinely clear.
Famous stories
Some of the best-known anecdotes in automotive history are folklore. Where a story is beloved but unproven — a letter, a nickname, a quote — we tell it and label it as disputed rather than dropping it or passing it off as fact.
Period imagery
Some imagery used in the films and on this site is illustrative rather than a photograph of the specific vehicle discussed. Archival photographs are credited where used.
Corrections
We get things wrong.
When that happens, the correction is made on the page and noted, and — where the error is substantive — acknowledged in the video’s comments. Viewers have already corrected details on this channel, and those corrections have improved the work.
If you’ve spotted something, say so. A source or a citation is enormously helpful, but a clear explanation of what’s wrong is welcome on its own.
Who makes this
Badges & Chrome is an independent research and documentary project. It is not affiliated with any law-enforcement agency, manufacturer, museum, or archive. No manufacturer or department has any input into what the films say.
