How is Yurt being biased? He simply states that there are not a lot of facts to go on. He's right.
Obviously I am in the minority about racial profiling but I really haven't seen a lot, if any, evidence that racial profiling or discrimination were involved in the police investigation. I'm not discounting the possibility and I certainly understand African Americans sensitivity to this issue. Zimmerman though is another case. I think it's obvious that he did racially profile Trayvon.
Note that wheter he is playing the devil's advocate or not, his comment are more defensive of Zim, than Martin.
