Hopefully this will put to rest the desperate allegations by Zimmerman defenders that Trayvon Martin instigated the physical confrontation that led to his death. Moreover, given that Zimmerman pursued a fleeing Trayvon Martin, Florida’s Stand Your Ground law will likely not provide immunity for the killing:

George Zimmerman, the Neighborhood Watch volunteer arrested yesterday in the fatal shooting of 17-year-old Trayvon Martin, faced a judge for the first time this afternoon. Meanwhile, a probable cause affidavit has been filed in the second-degree murder case. In the two-page document, prosecutors offer little new information about the shooting.

However, they said in the affidavit that “Zimmerman confronted Martin,” an apparent contradiction of Zimmerman’s version of the events that led to the shooting. The document says Trayvon’s mother identified the screams for help heard in a 911 call as those of her son. It also reveals that investigators interviewed a “friend” of Trayvon’s who was talking to him in the leadup to the shooting.

Based on the description, it appears the friend was the girl described by Martin family attorneys as his girlfriend. “During this time, Martin was on the phone with a friend and described to her what was happening,” the affidavit said. “The witness advised that Martin was scared because he was being followed through the complex by an unknown male and didn’t know why.”

Martin tried to run home, the affidavit says, but was followed by Zimmerman. “Zimmerman got out of his vehicle and followed Martin.” The affidavit goes on to say that “Zimmerman disregarded the police dispatcher” who told him to stop, and “continued to follow Martin who was trying to return to his home.” Zimmerman, the affidavit says, “confronted Martin and a struggle ensued.”

According to the affidavit: “Trayvon Martin’s mother has reviewed the 911 calls and identified the voice crying for help as Trayvon Martin’s. Zimmerman shot Martin in the chest.”

So while defenders of George Zimmerman point to Florida’s Stand Your Ground law to justify Zimmerman’s actions, given this new information, it would seem that Trayvon Martin was the only one of the two that could have availed himself of that defense had he survived.
