... what did you say?

OK I'm getting back to it after a bit of a lapse and it's amazing how much I have forgotten.
RSS is now in hand and rather than read library stuff I looked up the ABC science news and read an article about a lie detector which is used over the phone to detect social services cheats. There is contention about its reliability but it seems to be working as a deterrent in any case. It raises all sorts of moral issues.
