That's what DNA is for. And I just don't see any motive for even someone like Furhman (sp?) to plant that, or how he would've anyway.
The motive was explained..Hates blacks, doesn't like interracial couples, etc...
Now, I think that's flimsy and I think the undisputed facts (that the defense didn't even attempt to dispute) show him guilty. But, you can say that some level of doubt was raised and that's enough.
I mean look at the Sayed case. I personally don't think he did it but there is reason to think he did. That being said, no matter what you think, there is no way he should be in the jail. They proved next to nothing in that case and he still got convicted. You have to prove it.
