entrapment?

Law enforcement agencies operate websites with the intention of luring people who want access to illegal images. 

Since [this man] had “previously demonstrated an interest in obtaining child pornographic materials online,” he was tabbed to receive an unsolicited e-mail from an agent touting the undercover FBI web site. 

The website was designed to appeal to this particular interest, and to encourage someone to click the links.


How is this not entrapment? If the man had no way to find the website without an invitation from the FBI, then the FBI is the reason he tried to download child porn.
