he doesn't, lol, but its funny because he did just buy some illegally gained organs off the black market to return to the patient they were taken from. he's fairly legal in all other aspects, but he buys quality supplies cheap and relies primarily on smugglers, etc., to get those for him. sometimes it does mean he's in possession of illegally obtained goods (like, a shipment of syringes or whatnot might go "missing" from another ship during a sparrowhawk expedition and it usually ends up in kang's possession), but red tape and hospital politics is a crapshoot, so he works around the system. i'm all good with friendliness albeit kang isn't the most friendly person in the world (very serious, rarely escapes the medical clinic, works almost non-stop until his body tells him he needs to chill), and he could possibly use the connection for cybernetic parts versus organs.
