That's difficult - because it depends on the classification of "indecent". Which is subjective.<p>There are usually a few levels of "indecent image". Here in the UK we use the Copine scale which has 5 levels. Level 1 <i>includes</i> non/semi nudes but in an overtly sexual pose OR nudes but in a non-sexual pose.<p>Im not sure of the exact classification system used in the states but I think they do it similarly. The difference here is that if you only have a few level 1 images then you wont get prosecuted - i.e. these people wouldn't be prosecuted here. (based on that I am assuming that the US system is a bit more lenient about what is classed as indecent)
