Last year, the Arapahoe County authorities accused photographer James Grady of running "perhaps the largest child pornography ring in Colorado history"; he faced 886 charges that together would fetch almost 8,000 years in jail. By the time his case got to trial, though, the number of charges had dropped to 39, and the jury took hardly any time to find him innocent on all counts.
Can you blame them? It turns out the teens on Grady's website all had their clothes on, and all their pictures were taken with both the models' and their parents' permission. It's entirely possible that the photographer understood the law better than police and prosecutors did.
