I'm not speaking for Chilly, the A's nor Casey, but I found an interesting article yesterday (posted here on WS) that I wish I had 'bookmarked'.
Once I find it again, I will add.
The basic point of that article was that defense attorneys are not out to prove their clients innocent... especially the guilty one. In fact, the defense attorney's job is to make sure the prosecutors and law enforcement are doing their jobs in proving the accused is guilty.
So what's wrong with being critical of the "evidence" that's been released? We're not got going to be called upon as jurors, so what we think is irrelevant. But, I think we owe it to ourselves and each other to be a bit critical of the 'system' to ensure that our government never gets to the point to where it can incarcerate individuals based upon their own biased, unsubstantiated, unconfirmed beliefs about an individual.
