It would be better if they didn't announce this. Unless the government had some special reason for doing so, the bad guys now know that the phone contents are being reviewed.
Why does the government and press tell the world about special operations, drone strikes, and all the secret stuff that we would rather not have bad guys knowing?
This is always a big issue. It is less of the government's fault, and more of the press. The press is always looking for the smallest bit of information to release to the public through media. I totally agree though, the government has no benefit from announcing this to the public.
