The New York Post reports that he [New England Patriots' owner Robert Kraft] described the incident to the crowd at Carnegie HallÂs Medal of Excellence gala on Friday night [in 2005]. ÂI took out the [Superbowl championship] ring and showed it to [Putin], and he put it on and he goes, ÂI can kill someone with this ring. I put my hand out and he put it in his pocket, and three KGB guys got around him and walked out, he explained. KraftÂs attempt to get the 124-diamond bauble back were thwarted by representatives from the Bush the administration, who told him, ÂÂIt would really be in the best interest of US-Soviet relations if you meant to give the ring as a present. And there you have it.
It's from the NY Post so one has to be skeptical, but it fits with Putin's character - at least how he's generally portrayed in the US press...
Cheers,
Scott.
