I do think people should be given fair trials whenever possible...

Quick, who was doing the executing 10 Thermidor? Are they the sort of "radicals" I associate with? Or did I not tear them limb from limb in cookie form?
As to the Girondins, the law applied on the night of 9 Thermidor was the same that Saint-Just had put through earlier to speed the execution of the Girondins; those that had fled were declared outlaws and only needed to be identified to be executed.
