A bombshell new report from CBS News suggests that the Iranian Government has murdered between 12,000 and 20,000 protesters since the ongoing, national revolt against it began.
“Information trickling out of Iran on Tuesday suggests that a crackdown by authorities to end more than two weeks of widespread anti-government protests has likely been far more deadly than activists outside the country have reported,”
20,000 soldiers were killed on the first day of the Somme in WWI which involved literally mowing down rows of soldiers with machine gun. We would see plenty of evidence if this was happening to civilians in cities even without internet.
