Where NRDS = Not Red Don't Shoot?

Very few. CVA and the other holder alliances in Providence were, but they no longer control the region. Even when CVA did police Provi there were plenty of roaming gangs who would go there to hunt for kills.
There is a coalition in Great Wildlands that is NRDS, but there are plenty of reds that live and hunt there, so even if one set of occupants are NRDS, that does not mean they are the only force in the area.
Because of this, even if an area is nominally NRDS, to be safe-ish you have to assume that evey non-blue is a potential hostile. The only place outside of hisec where you are mostly safe is in NBSI sovreign space where you are a blue and there are no non-blues in local. This is why most alliances are NBSI, defend their space and have intel channels to report encroaching hostiles.
