*The mother of a 13-year-old eyewitness to the Trayvon Martin killing says a police investigator told her he didn’t buy shooter George Zimmerman’s claim of self-defense.

Cheryl Brown, accompanied by her attorney Alisa Adamson, appeared on both MSNBC’s “PoliticsNation with Al Sharpton” and “The Last Word with Lawrence O’Donnell” to talk about what her son saw that night, and his questioning by police after the killing.

“The lead investigator from the Sanford Police Department stood in my family room and told me this was absolutely not self-defense and they needed to prove it,” said Brown. “He told me, and I’m paraphrasing this quote, ‘Read between the lines. There’s some stereotyping going on here.’”

Brown said police did not contact her son about his 911 call until five days after the shooting. And when they did question him, Brown said she thought the questions were “leading.”

“I think there were some tactics used to maybe suggest some things to him, leading him to say certain things,” she said.
