Well, not every who's arrested is guilty of the crime for which he was charged. But I do see your point, and agree--to a point. But I live in a state where there's now a moratorium on the death penalty due to overzealous prosecution of defendants later exonerated by DNA evidence, so I am grateful for the efforts of defenders.
That said, I find everything about Baez to be slimy. His overstatement of his experience is very disturbing.
I don't find it at all disturbing, however, that BC and JB worked in the same office at the same time. There's nothing hinky about the association--it's just plain, old-fashioned networking.
