Resources about hate hoaxes used in the infowar against whites.

The following quotation is from the foreword of Crying Wolf: Hate Crime Hoaxes in America by Laird Wilcox:
This book grew out of a research project I began in 1988 when the issue of racist and anti-Semitic hoaxes first came to my attention in a serious way. I had learned in talking with a former associate in the civil rights movement of the 1960s that a cross-burning I had always assumed was done by white racists was, in fact, done by civil rights workers. This aroused my curiosity, and more extensive probing convinced me that it may not be an uncommon occurrence.
