This is part of what I recovered of the pictures that the Calgary Police Service (working with a private security company) forced me to "delete". Unfortunately, I seem to have permanently lost most of the image data (both missing whole images and most data in the two that survived). In a weird quirk, my camera's habit of frequently "freezing" and corrupting images, is what might have saved this image. My camera can't display corrupted images like this (I cropped out the bad part), so this appeared all black, during the review for images to be deleted. The good images, seem to be unrecoverable.
