I remember 2 [KNF] ships, 3 [Yakuza] and a bunch of indies. I'm sorry I have no screenshot as I was mostly busy getting shot by one of the Yakuza, and I didn't think of it at the time anyway.
To me it was very much reminiscent of the Corsair raids of Bretonia back in .84.
I'm taking a wild guess that it also came about in the same way: KNF (or these Yakuza people) deciding to raid Bretonia, raising the shout of who'd like to join, then steamrolling all over the place reveling in their PvP power in disregard of RP environment.
It might be my own faulty interpretation of the RP environment and if it is so, please correct me, but I'd expect large scale Kusari fleets to remain in the general area of the front lines (i.e. Taus, Leeds) and not within 10K of New London. At the very least outside previously coordinated large scale events.
I would take it as a kindness if this could be reinforced on the ranks of KNF and whoever you have influence over. Otherwise I'm pretty sure I could also pick a time when I could camp New Tokyo with a bunch of Bowex fighters greeting traders to Bretonian territory there, like it's been done to New London today.
