Something that happened many years ago when I was A Traveller Player and that may happen again is The Pcs faking surrendering to A Pirate, letting them dock and board then The Pcs using Poison Gas pumping booby traps that they've took the antidote to and claiming the pirate ship. What I want to know is how can they return to Imperial Space and claim legal ownership of A Ship registered as A Pirate Ship without being attacked by Navy Ships and either destroyed or captured and spaced without trial?
