Auction for gun George Zimmerman said he used on Trayvon Martin has a $65 million bid

Seems a bit much for a used glock don't you think? Whats your take on this. Apparently George Zimmerman is going to be Rich. Is he within his rights to sell a "murder" weapon or is he not. I wouldn't have used the term murder weapon before til I saw all the stories the guy was putting out to get attention for himself.
