Internet sleuths - 7/7 2005 london bombings - help needed

I've recently been reading up on the 2005 london bombings.

I was reading about how Sidique khan was a assistant school teacher and I then had a flash back to a public conversation I had online at least 5 years ago with someone who said they worked at the same school as Khan. They told me that he had told them about how he was helping with a drill in london. How exited he was but also wasn't really allowed to tell anyone about it.


Like I said. This was a public conversation. It was probably either here or over at davids forum, although I could be wrong.


Maybe this person was full of shit. Maybe they weren't.
I'd just like to re read over what was said (my memory is shite lol)
