A good little book on how messed up Oklahoma law enforcement can be.

Relates also to the race riots of 1921 — the chief of police of Tulsa was an outright criminal and provided no leadership or control during those riots. Look it up on Wikipedia.

I am sure there are many dedicated policemen in Oklahoma and mean no denigration of the present police forces, especially since one has just been killed in the line of duty, but I am starting on a new work that takes place largely in Oklahoma in 1870 and it started as a lawless territory and sometimes these beginnings are hard to overcome.
