Lots of it. This idea that Zimmerman was this wannabe cop who racistly pursued a poor innocent kid then shot him as soon as things go hot - it's Obama propaganda bro.
Zimmerman's black neighbor had been robbed and home invaded by teenagers earlier, and Zimmerman's neighborhood watch activities helped minimize the damage. Had Trayvon simply said, "Why are you following me?" Zimmerman would have asked what he was doing and they could have parted ways just fine.
Trayvon chose to sneak up on and beat Zimmerman - plenty of evidence for that - and ended up getting shot as a result.
You say you refuse to believe that it was anything other than the phoney narrative.
Why? You need to evaluate who you listen to in your life, and your critical thought process. This idea of Zimmerman as the racist out-to-get-you wannabe cop ONLY came from the race-baiters. Why have you adopted it as the only thing you're willing to believe?
