From ESPN.com :

Defense attorney Luis Galvan told the judge Thursday that Mosley, by going to Williams with the alleged tape and offering to counsel Richards, was actually trying to break out of small-time community activism and bask in the celebrity of Sheffield and his wife.

“He has tried to create a persona of being something of a poor man’s Jesse Jackson,” Galvan said. “He enjoys the limelight, judge, no question about it.”

If Mosley really were engaged in blackmail he would have asked for more money, Galvan said.
