I'm asserting that the evidence exists and that I have seen it. Before I saw it, I never for an instant doubted that it was happening.

To further clarify, because some others (not you) seem confused, just because terrorists are in fact using photos and videos to plan attacks, doesn't mean that we have to start reporting everyone we see holding a camera in public. Its entirely possible for profiling photographers to be a bad idea even if every single terrorist had a camera.
