Some activities are extremely asymmetrical, for example, you get merits for killing power ships and wanted ships in your own territory but are considered a criminal if you attack enemy power ships in their territory.
The Q&A talked about Power security, but did not touch these changes at all:
Will there be any changes to the crime and punishment system?
There have been some additions to the crime and punishment system relating specifically to Power NPC Agents and crimes against other Powers for example we have PP security in controlled systems now, these will attack you if they find out you're not aligned with them, but normal security wont attack you for the same thing. However the overall crime and punishment system will stay the same.
It's such a harsh C&P change to be getting local police and local faction bounties for attacking enemy power ships in their territory, while the concept of power bounties (which do not attract local police) seems to have been completely dropped, but the power board is still shown with old PP1 bounties. I'd consider the current behavior to be a bug, but I do not see an issue report for it.
