"Trayvon Martin was not an innocent child. He was a 17-year-old juvenile delinquent of considerable size. Martin was a violent youth and had been arrested previously including while in possession of burglary tools. He was temporarily staying at his birth mother's residence after being suspended from high school. The judge refused to allow any of his school or criminal records to be admitted, but Zimmerman's attorneys fought hard to introduce evidence of THC being in his system and numerous texts. The text messages recounted a fight where Martin beat his opponent and his brother asking him when he will teach him to brawl so well. There were also Facebook posts where a gun is brandished and Martin is acting like a gang banger. Judge Debra Steinberg-Nelson, however, refused to permit any of this evidence in as well citing the defense could not prove someone else did not have access to his phone or FB account. This infuriated Don West and rightfully so. The prosecution deliberately withheld critical information to validate Martin was indeed the person who posted the texts and photos. Furthermore, the jury is commonly allowed to determine whether the evidence is probative or not. I know many prisoners where the prosecution was allowed to introduce incriminating computer or phone data despite not being able to confirm the source. In fact, a man I speak to regularly was convicted based partly on Google searches made on his girlfriend's computer."
