The Washington Post is doing some great work these days with their Fact Checker feature, which is digging into all kinds of "statistics" being thrown around out there to see where the figures come from and whether there's any truth to them. Think of it as the rhetoric version of that TV show Mythbusters.
Today's myth-busting was around the "fact" that 300,000 U.S. children are at risk of sexual exploitation. Take a look at how they tested those figures and what they found out - fascinating stuff, and all of it underlining that we need to be very, very careful in deciding what to believe when topics are highly emotional and potentially divisive. That old adage about believing half of what you see and none of what you hear has never been truer.
