Both Too Stupid and Too Evil To Stay Out of Prison

That there are people this evil does not surprise me.  That they are so stupid as to advertise this crime just astonishes me.  From August 13, 2013 KIVI-TV:

U.S. Attorney Wendy Olson said Tuesday that Jason Lloyd Schaber, 40, of Boise, was sentenced in United States District Court to 30 years in prison, followed by lifetime supervised release -- after pleaded guilty in May to sexual exploitation of children by producing and distributing child pornography.

According to the plea agreement, the investigation of Schaber's activities began in April, 2012, after Boise Police were contacted by a person who saw a Craigslist advertisement offering a 3-year-old child for prostitution. Investigators worked with Craigslist and Google and traced the ad back to Schaber in mid-May, according to reports. Boise Police investigators obtained a warrant to search Schaber's home, which they executed on May 31, 2012.

How stupid do you have to be to think that placing an ad for a crime like this isn't going to get you attention from prosecutors?
