I should add
All of which is not to say that I don't believe that there is unbelievably vile shit that goes on right under our safe domestic noses, including sex trafficking. I'm saying that Landesman did a crappy job of making his case for it (I believe and I don't know), I'm pissed because I think it's important, and even if the exact numbers aren't worth fighting over, the orders of magnitude actually do matter, and pulling a number out of one's ass doesn't help anybody.
I thought Jack Shafer got it right (I'm a fan of his, actually, from his time at DC City Paper). Who is Landesman? Has he done investigative features for the NYTM before?
