well guys, it's over
and i'm afraid it's not all that exciting!
i had my meeting with the headmaster
he tried to persuade me to do it again with the same old lines. 'it's not a fingerprint
the server is secure etc etc
i told him why i wasn't going to do it
and he even said he agreed
with my anxieties about government invasion of privacy, increasing surveillance, police state, 1984 etc
when I told him I felt that he should respect my position. he said the reason they have been applying so much pressure is for 'efficiency' and conformity reasons.
and then he very fairly said to me that nobody was going to force me to do it, and that that is the end of the matter.
so yay I win, even though it didn't get really dramatic
thanks again guys
