I'm pretty sure that if you need ubiquitous surveillance to ensure that your citizens don't commit crimes, you don't have a high-trust society, by definition.

Surveillance and a high trust society are diametrically opposed concepts. You don’t need a high trust society if you have total surveillance and vice versa.

I don't think you understand what "high trust" means. High trust societies have no need for surveillance which is what makes them high trust.
