How to Do Good Research

I'll give you a perfect example, fully documented, from the Martin Luther King case (with quotes and references) :

Dr. William F. Pepper is an absolutely unimpeachable source on the King case - he was a personal friend of Martin Luther King, and has spent 40 years (on and off) involved with the investigation of his death - he has written not one but three books on the case, and argued the case TWICE before a Jury, once in a mock TV trial, once in a Civil Trial (King Family vs. Jowers et al., 1999), where he proved before a jury that the US Government killed Martin Luther King.

In Pepper's first book, Orders to Kill, he quotes former Memphis Police Chief Sam Evans regarding King's "friend", SCLC Minister Rev. Samuel "Billie" Kyles, stating that Kyles was one of his paid informants.

Kyles was a Memphis Police Dept. informant in 1968, at the time of the killing of King. 

FACT.

Shadow Government Shill author Gerald Posner comes along and writes a book subsequent to Pepper, Orders to Kill (1995), in which he quotes Kyles and attacks Pepper as being motivated by money:

"In his book, Pepper raises the strong inference that Kyles might have been an FBI informant; 'Its's degrading and insulting' says Kyles, 'and casts aspersions over my forty years in the Civil Rights movement - I've seen how Pepper operates."

Now - can you see where the cracks are....?

He's denying something he was never even accused of. And it's precisely the same here.

This person is a Police Agent. You are accusing them of being an MI5 agent.

That's absolutely untrue.
