Aha, what does my post number have to do with anything? The statement was about evidence between Templar and Guards. Not Templars and Mages. Kirkwall extreme situation or not showed that under strict Templar leadership it is more likely for Templars to abuse their power than city guards.
Two things:
1-In order to use Kirkwall as an example, you'd first have to prove that there were more incidents of abuse of power within the Templars than within the City Guard.
Both had rapists in their ranks and both has corrupt leaders altough Meredith honestly sought to protect people while the Guard Captain before Aveline was sacrificing his people to deliver info to the gangs.
2-If you did manage to prove that, it still wouldn't be valid because we should compare a city where the Knight Commander effectivelly took over with one where the Guard Captain did rather than compare Templars and guards operating under different circunstances which would, naturally, affect their behavior.
