Safe Sincerity
Author really doesn't understand how royalty works and clearly doesn't understand that servants are servants, no matter who's backing them and making them spy, they are still just servants and will still get executed if anyone even suspects them of snooping. Why do you think there were so many spies? Why do you think spies were paid so well? Why do you think people STILL refused to take bribes, even when the money offered were extreme? It's because it's basically guaranteed death within the month, unless they are simply saying what they see along their normal working hours, and even then, if they see something they shouldn't, even if they aren't at fault, they'd still get killed. Having guards barge into the bedroom of a prince and stuff is just absurd.
