Sounds like some real nice people.
A couple of points. For one thing, I tend to assume that cops will always overstate the details of the crimes they stop, and prosecutors doubly so. I'd be willing to bet that, while certainly detestable, what they stopped probably wasn't as uniformly evil as they claim.
Another thing, why is this within the scope of DHS? ICE? A lot of people, myself included, said all along that there's no way that if you create an organization with this much power, there's no way they're going to stop at protecting us from foreign threats. Kiddy porn rings are popular busts and low-lying fruit, so people will cheer this expansion of power. Drugs will certainly be one of their foci, as well. See where this is going?
