Ok I went to a Nav Beacon and took on a few pirates, I saw a guy who had scanned me so I scanned him back with my Kill Bounty Scanner, he was down as Clean but when I used my bounty scanner I saw he had a 19,000 CR bounty on his head. So I thought he was fair game! All hell broke loose, everyone attacked me and I was given a 300CR bounty on my head! I got the hell out of there as about 20 NPC ships were attacking me. I used silent running to get back to the station and wiped my 300 bounty. But why did I get a bounty for attacking someone who had a bounty on his head?
