Prophet Muhammad Cartoons - timeline question

I was puzzled by something, and the Times’ (UK) otherwise useful timeline of the brouhaha has still not helped: http://www.timesonline.co.uk/article/0,,13509-2021760,00.html

So … why did all of those European papers decide to reprint the cartoons on the same day (Feb. 1)? Did they have a conference call or something? There seems to be no particular outstanding event the day (or two) before that would have suddenly compelled them all to print the cartoons in response, and Feb. 1 wasn’t even a Monday, or anything–it was a Wednesday. Why did they all choose to run the reprints on the same, otherwise unremarkable, day?

The two days before, the profile of the story was raised by the introduction of violence or the threat of violence. Masked gunmen, bomb threats – now that’s worth some ink. Maybe even a pictorial.

I can’t make up my mind whether or not the logic is perfectly perverse or entirely sensible.

Yup. Your timeline only says who published what when. Add in who protested in what way when, and it becomes… well… let’s say non-random.
