Let things run their course...
Why retain more lawyers? The investigation will be over when it's over and there's nothing any of us, either singly or in concert, can do to shorten it. Getting more lawyers in the mix does nothing but cost people more money and lengthen the investigation...
Think about lawyers for a minute, if you will...How do they charge people? It's not by the job; it's by the hour and by every piece of correspondence they create (even correspodence within their own offices). Lawyers have no desire for things to end quickly because every minute they spend dragging it out results in major $$$ for them. The last thing any of us needs to do is involve any more lawyers in this matter.
Just my two cents...
