Why I wrote about Byers, the confidential informant

Some readers have asked why I posted the article below at this time. The answer is that it was prompted by two other articles dealing with confidential informants that I wrote recently for the Arkansas Times: Bullet in the back and a related piece, Death under cover. The obscurity that surrounds confidential informants and their relationships with police has clouded aspects of both of my books and figured in much of my reporting.
