If you are full green (actually half a bar from full green) to the NPCs, they will not turn hostile to you no matter how many CDs you fire.
Note 2 things:
a) If there are NPCs which are allied to your own, but you are not fully green to them, these will get hostile to you and also change your own NPC so hostile
- so to avoid issues as a police officer in liberty you have to be fully green to LPI, LN and all trade corporations
b) In some areas (Liberty) you can actually kill NPCs with a few cds, if you kill enough of them (2-3) your reputation drops below the threshold and they get hostile to you.
