I don't deny you that point, but I say the right of self defense cannot be invalidated by Anything. Self defense overrides any system of law or crime and punishment. See also this post...
In the UK if you kill someone in self-defense you'll still be arrested and questions by the police. Some folks have even been put on trial for shooting intruders in their own homes.
It's not as black & white as you're making out.
In any system - virtual or real - where there is law enforcement - law enforcement will attend the scene of a reported crime.
If violence is happening when the police get there, their first priority is to find out what's going on. In the real world it'll be to stop the violence happening then sort out who's at fault for what.
In ED - the police arrive when a crime has been reported and they investigate to see who's Wanted, then their actions depend on that.
Once again - in star systems with Law, the police should always investigate when violence is reported - otherwise all star systems might just as well be Anarchies.
Look, the system now is really simple. Either have RCAM on or off, and it's the player's responsibility to decide which and deal with the consequences of their decision. It can be a double-edged sword.
And this suggestion and the other thread is based on an assumption - a naive one at that - that all players in Open, whether they're PvP'ers or not - are honourable. Well, they're not.
A "report crime but don't send the po-po" toggle would basically render star systems with Law to be like Anarchies. It's the "make this system Anarchy anyway" toggle. It goes against the concept of a place with Law in which police investigate reported crime.
You want an 'honourable' fight with other PvP'ers, you do it in star systems without Law, or you make sure your oppoent also has their RCAM switched off.
I'd fully support Frontier adding indication of a player's RCAM status on the HUD by the way - that'd be a very simple and quick way to solve this entire problem, without effectively turning every star system with Law into the equivalent of an Anarchy, without adding any further complication to Frontier's crime detection code (seriously - you might think of it as Just Another Toggle binary variable, but adding yet another variable into a decision-making algoryth can introduce unintended consequences in code).
In summary - I object to this suggestion because there are already existing solutions, RCAM is a double-edged sword which adds nuance to the game in terms of consequences for making the wrong decision, and I don't want star systems with Law to effectively be the equivalent of Anarchies. I do however reckon Frontier should definitely add RCAM status to the HUD for other players to see - think of it as a system-wide broadcast beacon which not only can summons Po-Po, but also acts as a warning to every other ship that Law Enforcement WILL be notified - or not.
