No overt threat?

According to the media and the government, the new Bin Laden tape provides "no overt threat".

The new video of al-Qaida leader bin Laden - his first in three years - runs nearly 30 minutes long, said the government official who has seen a transcript of its contents and spoke on condition of anonymity because it has not been made public.

Bin Laden makes "no overt threat" in the video, the official said.

I would think the very existence of the tape would be considered an "overt threat".
