I never claimed to know there were definitely 12,000 deaths. How could I? No one knows the exact number of deaths so far.
My thread was about how over 12,000 people were feared dead. And I provided my sources for that estimate. For anyone who may not have seen that thread, I said A source inside Iran who was able to call out told CBS News on Tuesday that activist groups working to compile a full death toll from the protests, based on reports from medical officials across the country, believed the toll was at least 12,000, and possibly as high as 20,000.
I also posted that The opposition Iran International television network said Tuesday that its information suggested about 12,000 people were killed. A source in Washington with contacts in Iran told CBS News on Tuesday that a credible source had told him the toll was likely between 10,000 and 12,000.
How can we have definite numbers when the internet has been cut off for so many days? But it's generally considered that the number of deaths once established will be way higher than the verified deaths we know about so far.
Britain's Foreign Secretary Yvette Cooper said in Parliament on Tuesday that her fear is that the number of deaths may prove to be significantly higher than the deaths that have been officially verified so far (currently standing at over 2,500).
Unlike you, I didn't post these numbers as fact but as the estimates of informed people inside Iran. By contrast you read a post on X and present it as fact.
