I’ll have to wait before drawing any conclusions. On the one hand, the kid is a creep. On the other, the FIB’s reputation in such matters is more than a little tarnished. Vicky Weaver isn’t around to ask if they go after people’s families, for example. On the third hand, blackmailers usually like to work in the dark and this one was published to the world. If they prosecute, maybe it’s legit.
That is a very wise policy.
