Um, no. This is yet another piece of redistributed drivel that's at least 15 years old. Jeez; could you first exercise the finely-honed critical faculties you developed as a lawyer before sharing this stuff with us (and all the other boards on OH--WTF?). This is only slightly more stale than someone who came across a DVD remainder bin, watched "An Inconvenient Truth", and immediately xposted to all the boards on OH to warn us all about "global warming". Most of your audience hasn't been living under a rock for the past few decades.
rBST doesn't cause precocious puberty (or anything else) in children. It's controversial only because it allows a cow to produce much more milk than normal, but such "super cows" have an increased incidence of mastitis, a condition that requires treatment with antibiotics. I believe this is what was summarized for you in TT.
Milk from cows treated with rBST cannot be distinguished from milk from untreated cows; rBST isn't secreted into milk, and the hand-waving arguments that milk from cows treated with rBST contains higher levels of IGF-1 is really grasping for straws. If there are any traces of IGF-1 in milk, and there is no evidence that milk from cows treated with rBST differs from milk from untreated cows in the respect, it's at the level of detection, and it certainly doesn't have any physiological activity. (You could drink a rBST or IGF-1 milk shake, and it wouldn't have any effect, because you'd digest these proteins as food; they don't have any oral activity in massive doses, let alone in minute, homeopathic doses.)
Needless to say, no children have been harmed (or have started puberty early) after drinking milk, whether it comes from rBST-treated herds or not.
Since milk from treated and untreated herds cannot be distinguished , this is not a scientific controversy; it's effectively an aesthetic or religious controversy. (Transubstantiaion: substance versus accidents, kosher versus non-kosher, organic versus non-organic, etc.) As it is, many dairies have labelled their products as coming from farmers who "promise" that they don't use rBST on their herds. Since there's no effective way to test this in the dairy end-products for sale, dairies simply pass on that "promise" from the farmers to consumers. Most consumers who wish to avoid milk from rBST-treated herds have used this labelling quite effectively for the past decade or so.
