Too soon to know. I haven't seen him do much lawyering, other than in the PR aspect that's so prevalent in this case. The A's are keeping silent and he is so far able to speak for them, as a representative is supposed to do. He himself presents a nice and sympathetic figure, but that may not persuade people if the message from the A's stays the same. It does seem he was more acceptable than Mr. N because he will carry forth the Casey banner, as the A's apparently wish. That seems odd, coming from their attorney, who for some reason felt the need in one of his first public statements to suggest the A's need and want immunity as part of their new leaf of cooperating with LE.
Maybe it's a defense attorney thing, but there seems to be some prevalent idea that the best way to garner sympathy for a client is to publicly suggest they have been unfairly treated by LE. Nothing would be further from the truth in the case of the A's. How many times is he going to go on TV and misstate that they can't visit Casey because the tapes will be on television the next day, and they wish to see her in private? He knows well and good how most of the tapes that were released came to be released, and when, and he knows the rules at the jail.
Having written all this, I guess the thing I notice is that everything gets taken to the public forum, rather than proper channels. If you want or need immunity, which suggests a degree of jeopardy for your clients, go privately to the state and LE and discuss it. If you feel they are wrongfully being deprived of a special jail visiting privilege, file a motion with the court and make an official request, stating your case. Why does an attorney even have to be out in front of the cameras with an A spin on every event that occurs? Oh, well.
