Your analysis is strong, and I think you could push it even further by looking at how people interpret missing metadata. You mention that the metadata could not be checked, but it might help to point out that most platforms automatically strip metadata when images are uploaded. Because of that, the absence of metadata does not suggest anything suspicious on its own. What matters more is what your sources actually found. Neither Reuters nor Snopes uncovered any sign that the firearm photo existed online before the incident, and neither found evidence of AI manipulation or editing. That makes the Reddit screenshot even weaker as proof, since reverse image search results do not establish when an image first appeared. Your conclusion that the claim is exaggerated or misleading fits the evidence well, and emphasizing how unreliable the supporting “evidence” is would make your argument even stronger.
