On day seven of the George Zimmerman trial over the death of Trayvon Martin, the court listened to Zimmerman’s 911 phone call, watched his reenactment of the incident and heard testimony from two people – Chris Serino, the lead investigator in the case, and Mark Osterman, a friend of Zimmerman and author of Defending Our Friend: The Most Hated Man in America.

The court played Zimmerman’s 911 call while Serino was on the stand. In one part of the phone call, Zimmerman said, “These [expletives] always get away." Serino said that the language used was one of spite and ill will. Serino then asked Zimmerman what was behind his statement “these [expletives].” Zimmerman explained that he was referring to individuals who victimize the neighborhood.

Serino testified that there was no evidence of Martin being armed or committing a crime on February 26, 2012, the day of the shooting. He also said that he suspects Zimmerman exaggerated some parts of the altercations. However, Serino said that he was always compliant when they spoke.

Osterman wrote Defending our Friend: The Most Hated Man in America based on what Zimmerman told him about the shooting. He said that he did not make anything up in the book, but he didn’t write it until four months after the incident. He did not take notes on what Zimmerman had told him, didn’t follow-up on their conversation and didn’t show Zimmerman a draft of the book before publishing. “We were not able to contact each other after he was arrested the first time," Osterman said.

Osterman also said that if evidence suggested something in his book was incorrect, he would defer to the evidence. One such instance occurred today – Osterman wrote that Zimmerman had pinned Martin’s hands down, but his body was found with his hands underneath him.

A member of law enforcement for 21 years, Osterman was the person who had encouraged Zimmerman to buy a gun in the first place. “He asked whether he should or shouldn't, to start with, and I recommended that he should. Anybody who's a non-convicted felon should carry a firearm…. The police aren't always there," Osterman said.
