This happens all the time. The buyer has to to do their due diligence to insure that the ownership is legit and that that all is inspected and sound before buying. Just like in real estate there is an inspection period and right to cancel before closing...and those are contracts were this safety is written in. When it comes to verbal and informal off-the-cuff/street contracts I think that there is never really any safety net for anyone. This whole concept/conflict is the reason judicial government exists.
You're really losing me here I'm afraid. Whats the point of telling us about real estate law, why you think the "judicial government exists", the principle of caveat emptor, etc.
The point I and others have tried to convey to you is that your original post and assertions there in were incorrect. The Apple employees could have promised the OP anything, even if the OP had these promises written in a notarised contract with Obama himself as witness and several video's/recordings as evidence.
The one and only fact that matters is wether the OP had legal title to the machine. If its stolen, any promises, contracts, etc are null and void. Even if the Apple employee lied to the OP, it still doesn't make that contract enforceable, because the OP has no rights to that machine. It is entirely the OP's problem the moment it becomes apparent he has no legal title to the machine.
I'm sorry to labour this point, but misinformation such as your original post is likely to give the OP false hope. It is also possible other readers may foolishly believe there is a get out should they fall victim to a similar scam, by following the OP's example and your advice. It needs to be made absolutely clear to anyone reading this thread, no matter what promises you obtain from a third party to buy a stolen item in your possession, they are not enforceable.
It is you that will be left holding the can and your only recourse is against the person that scammed you. Even if you are lucky enough to pass the buck, sell the machine to some un-suspecting person, they would have every right to demand their money back once they discovered the machine was stolen.
OP the only thing you need to establish with Apple is if the machine is definitely stolen. (Since they advised you to call the police it appears to be the case). If it is, Apple are completely of the Hook and perfectly within their rights to recover the laptop. Even if they had to lie to you to do so. Your ONLY recourse is now against the craigs list seller.
