From Philip Coutts:
Do you envisage Powerplay as a tool to raise the amount of PvP currently happening? It seems that you are giving carte blanche to attack anyone from a different faction to you, regardless if they are wanted or not. Is there not a danger that the inhabited parts of the galaxy end up as one big warzone?
The carte blanche only exists within systems controlled by your Power and only apply against ships that are aligned with a Power of a different major faction to your Power. Powers interact with each other in different ways and combat is but one of those methods. How the Power is structured geographically will also guide which areas are potential hotspots. In some case Powers could provide a safety zone within their borders by their actions.
