I wrote my own thoughts on this story and respectfully disagreed with you (but linked to you! ;)). I don't think it has anything to do with birth control/abstinence only, at least not in this instance.

First off, did you know that the community in question just had a whole brouhaha last month over the local hospital's refusal to support a proposal to distribute contraceptives in the school without parental consent? To me, this indicates some sort of a link between not providing contraception and a high teen pregnancy rate. Secondly, it seems now that the "pact" might have been a myth, and that really it may have just been a bunch of girls who got pregnant accidentally: http://www.cnn.com/2008/US/06/22/pregnancy.pact.ap/index.html Even if the pact WAS real, and even without the knowledge of the town's previous contraception controversy-- sex ed isn't about handing out condoms and covering your eyes. It's about telling kids honestly and completely about what their choices could mean for them. For me, it's clear that these girls didn't get that kind of talk in school. And thus, in my opinion, they didn't get true sexual education, and the school needs to do more in this department.
