Thing is, a C&P system won't actually stop one CMDR killing another, it just gives them a more exciting after effect. The vibe on the forums is that it will somehow magically prevent player kills, but that won't happen because whilst it won't ever be a foucs of the game Frontier want it to remain a viable part of gameplay. Accordingly, a player who wants to kill another one will always be able to and likely won't care about the fallout.
Best thing OP is either to bring some guns to the party, or even better some wing mates with guns or switch to a mode where it's less dangerous.
Don't mean to sound uncaring of your plight, I had my weaponless tin can popped out in the ruins a week or two ago, but that's part of and always will be part of Open whether people like it, love it, hate it or care not a jot.
