A police officer does not usually know (or care) the race of the person's stolen car they are retrieving. Like I said before -- he was doing his job. it wasn't elite police skills that got your car back, but stupidity on behalf of those who stole it by leaving it somewhere easy to find. if you want to invite him over, then by all means do so..but if for any reason you don't, you shouldn't be forced to do so. If you're worried your wife might think harshly towards you for not inviting him over, just explain to her calmly and clearly why you don't want to..or if that isn't good enough and you don't mind lieing to her a little, you could just say he turned the offer down.
