One Day in September

I believe that what happened at the 1972 Olympics established a template for a good deal of future terrorist activity. This incident demonstrated for the first time that you could gain a world stage and the world's attention by committing an atrocity. The press has played a tacit role in terrorism since that time. Terrorists are looking for media coverage and know that the best way to get that is by executing attacks at prominent events or on large population centers.

Re. the film, the fact that the German security forces were unprepared is no surprise as there was no precedent for this type of incident in the past. Sadly, many countries including most western countries are quite prepared now.
