For the most part, a sting operation is inherently wrong because the only people it can sting are people who demonstrate willingness toward a voluntary transaction (drugs, prostitution), in which case it shouldn't be considered a crime at all.

This is an interesting case though, since it specifically targets people making voluntary transactions with people that are unqualified to make them (children). How personally, I think children should be allowed to make sexual decisions at the age of physical maturation or shortly thereafter (around 13-14), and if everyone and their brother wasn't so damned afraid of sex we'd probably have fewer perverts and young sexual experiences would be less traumatizing, but if we should consider screwing a twelve year old to be criminal, this act seems pretty good at identifying potential violence.
