Yes, I believe the evidence.
No, you believe the *conclusions*, not the evidence.
Evidence is what it is. It is the *conclusions* that are *drawn* from the evidence that are 'believed' or not and those go both ways.
But, your choice of words to conflate evidence and conclusions are common when one wants to make their case seem stronger than it really is.
Or maybe OJ really didn't do it.
You know what I'm saying?
