Here is an article already about the Padilla matter.
I read the article earlier but am just reading comments.
From this article:
The documents said al-Qaida officials were skeptical of Padilla’s ability to set off a dirty bomb but were very interested in the apartment operation.
I'm pretty sure this is NOT accurate. I believe Comey said the "Al Qaeda officials" were skeptical of the ability of Padilla to set off a nuclear device and they suggested the dirty bomb as an alternative. Padilla was hellbent on detonating a bomb.
We need the transcript.
Indeed, he was also interested in the apartment operation, but protested that the simultaneous explosion of 20 complexes was beyond his ability. He said he could manage 2 or 3 at once.
