I wrote about the film director who was recently exposed to have been an informant in the directors' school - he was 'netted' in the pre-emptive arrests before March 15, 1957.
There was always some trouble in the following years too, the biggest in 1972, when hundreds were beaten and arrested (I just learnt today that my mother took part in an illegal march that day, but not the one police attacked).
Two of the three biggest demonstrations during the changes in Hungary were on March 15 1988 and 1989. *Lunatic*, n. One whose delusions are out of fashion.
