Bs. I live in Paris. There is no evidence at all of 4 km or your other claims. The total number of executions in France during the Reign of Terror is estimated at around 16,000 to 40,000, with about 2,600 to 3,000 executions in Paris alone. Paris's population at the time was roughly 600,000, so the percentage of Parisians who died by execution was closer to 0.5%, not 30%.
