Using deception to arrest dangerous individuals. Personally, I don't have a problem with the idea.
It's not entrapment, that would mean that Dateline was coercing people into performing actions they wouldn't do otherwise. These predators are all too eager to go and have sex with what they think is a young child. It's comparable to a police officer going undercover as a prostitute in order to catch solicitors (granted, prostitution isn't nearly on the same level as having sex with a minor).
If Dateline didn't lure the predators to their trap-house, these pedophiles would have just tried to get with a real child
