Planning bombs for the Stock Exchange is rightly something to bring to trial, but, really, looking at the tourist stuff?

Their car was bugged as they made this reconnaissance, and they were talking about which building to "hit."

If that's so, then I have no problem, but the earlier reports - indeed any report I've yet read - didn't say that. They only talked about Johnson, the American embassy and two rabbis as a written list, and the stock exchange as a chosen target.

'Observing' is a tricky word, since it covers everything from walking past and looking at something exactly as an ordinary tourist would, through to getting the theodolites out and taking measurements. So I want better evidence than a vague declaration someone was observing something. A recording that they were actively discussing bombing the buildings so observed is such evidence.
