From Schneier's blog comes this:

Watch the video of how the Australian authorities react when someone -- dressed either as an American or Arab tourist -- films the Sydney Harbor Bridge and a nuclear reactor.

The synopsis: The Arab is intercepted within three minutes both times, while the U.S. tourist is given instructions on how to get inside the nuclear facility.

By the way, Lucas Heights is a research reactor. It produces medical isotopes and performs research, and doesn't produce power.

I've never watched The Chaser before until now; vaguely entertaining in a Candid Camera way but that's some pretty scary stuff there

These guys do some great stuff, that was gold!

Hah, as it happens I was trying to find this video last week (and failed to find it). Thanks! :)
