"CFTC Looking Into London Gold, Silver Price Setting" http://online.wsj.com/article/SB10001424127887324077704578358381575462340.html I have no idea if this will be seriously probed or (if) the PM-equivalent of LIBOR, but still it's today's news. Gary Gensler has been tough on others...
Gensler talks tough but 4 yrs into the silver investigation and... nothing one way or the other. expect more of the same.
