Not to scare, but I remember reading a story a few months back about the FBI setting up fake child porn links and prosecuting on basis of attempted access. Specific story in mind was a doctoral student at Temple University. Stay away from that crap.
"Vosburgh was charged with violating federal law, which criminalizes "attempts" to download child pornography with up to 10 years in prison. Last November, a jury found Vosburgh guilty on that count, and a sentencing hearing is scheduled for April 22, at which point Vosburgh could face three to four years in prison."
