A lot of non-law-enforcement related greetings are sneaking their way into Greeting 0.
This means that the vanilla Oath of Silence at the top of Greeting 1 is sometimes not being triggered correctly (aka, when just about anyone talks to you: exceptions being some forcegreetings and some quests that use Greetings to continue an encounter).
