@blatham,
It was quite funny - in the retrospective: there were some discussions about the possibility of the
Emergency Acts in the media, and we discussed it during lessons at school. I wanted to know what it really was about, wrote to a federal permanent secretary (distant family acquaintance), got the draw written by him ....
The water canon thing was stupid: was on my way to England by train, knew from the years before that the train stopped nearly an hour in Cologne main station, went out to watch the demonstration ... wrong place, wrong time.
But the girl in England later wasn't related to the Beach Boys!
