A case can be made for arresting someone who likes child sex toys, and letting him do whatever he wants, since it's a plastic toy.
However, if someone watching child sex movies or photos is charged despite those technically just being bits and bytes and he had nothing to do with making the movie, then a child sex toy perv should be charged too.
But then again, taking drugs, selling drugs, and killing is illegal.
But nobody seems to have a problem with everyone watching movies or playing video games and killing 1,000s of people. Or Grand Theft Auto which is everything you can ask for.... killing cops, innocent people, drugs, crime, hijacking cars etc...
