I agree, and I think that's why the Accords need Harry. It was foreshadowed after all - the cover-up felt like a bit of a backtrack to imply the truth isn't quite coming out, it's just seeping out.
Major news networks will cast doubt on the images because someone else had the scoop, others will say it's true, the whole thing gets talked to death, and in the end everyone will know the truth.
But - what truth? Non-human humans exist is quite a different truth than 'there is a whole supernatural world'. The former should become clear if strange, the latter will take much longer outside Chicago.
