DHS Official Charged in Sex Case

AP:

MIAMI - The deputy press secretary for the U.S. Department of Homeland Security was charged with using a computer to seduce a child after authorities said he struck up sexual conversations with an undercover detective posing as a 14-year-old girl.

If it's not really a minor, but a detective posing as a minor, but the pervert thinks it's a minor, shouldn't he be charged with a thought crime?
