A teenage couple in high school (just barely underage) were both charged with possession and production of CSAM because they sent images between each other. As I understand it from the local papers they ended up getting off fairly easy with something like 100 hours of community service. But only because our local prosecutor understood that they were kids, a couple, and sharing between each other, and almost of age to begin with. If we had a prosecutor less understanding they would have been facing at least 5 years in prison each.
