WHY WERE THESE PHOTOS WITHHELD UNTIL NOW?

Some pictures have finally been published that vindicate Israel in the flotilla case a year earlier:

Only now, more than a year after the violent flotilla incident in which terrorists tried to run Israel's blockade of Gaza, has it been conclusively shown that some of the "humanitarian" flotilla participants were armed with guns.

Photos of passengers on the Marmara ship sporting the guns were published on Tuesday in the Yediot Acharonot daily. It is not clear why the photos were not published until now.

I'm sure there are a lot of valid questions waiting for answers about why important evidence has been withheld for at least a year before finally being published. Was even Yediot trying to aid Israel's enemies by withholding the data?
