I think Edie was using Walsh as a cover. He's been successful in getting the word out about criminals and capturing them. However in this instance the media has released vital information that wasn't supposed to be given out and may have hampered the investigation. Walsh imo, would NEVER do that.
She seemed to be trying to defend the irresponsible behavior of the media by grabbing at Walsh's success as an excuse.
I totally agree, that's why I said the media is a good medium to release INFORMATION to the public versus EVIDENCE to the public. It was not a particularly good or pertinent analogy.
