Here is a really good in-depth 7 page Register article covering many aspects of the case:

It troubles me that the world is becoming so brainwashed that they want to shift blame to one single person. A scape goat.
Others have suggested that Amero's crime was not deliberately going to porn sites, but simply failing to prevent the pop-ups from being seen by the students. Indeed, this may have been the government's theory as well, or an alternate theory that the government came up with after the defense tried to show the existence of pop-ups and spyware. The prosecutor told the jury that Amero was guilty of exposing the children to pornography because she "should have thrown a sweater over the monitor" as a means of protecting the students. The angora defense? This despite the fact that as at least one student testified, the substitute teacher "physically reached up and pushed his face away from her computer".
Indeed, it is possible that the statute permits conviction for merely "permitting" a child to be placed in a situation that might impair their morals. So did the jury convict her for merely pushing the kids away and not yanking the extension cord? It is impossible to say. We all know that Microsoft Windows almost yells at you if you try to turn of your computer this way (well, at least when you reboot) – and that this kind of hard reboot can not only lose important data but can potentially damage the spinning hard drive.
If she can be convicted of a felony and do many years of hard time for child endangerment just because she failed to think fast enough to turn the computer off when a piece of spyware that may have been already on her machine started popping up porn images then I have serious issues. Not because I don't think our children shouldn't be protected because I really think they should. What I have a problem with is who is being blamed for this.
I have had problems for a long time with schools even having direct connections to the internet. K-12 schools should have completely private WAN network connections and no direct connections to the Internet. Just having those connections should get the school itself a child endangerment conviction if you ask me. After all the Internet *is* made of of 92% porn and we all no that no matter how hard you try to filter things out there are people out there who can get around the filters on both ends of the line (kids are smarter than teachers when it comes to computers).
I'm sorry, that's just the way it is. If you are going to have a 12 year old insecure operating system hooked up to a bucket of porn in the classroom you are the one who should be in prison, not this poor teacher. At least use an operating system that isn't so susceptible to this garbage, and keep it updated, and make at least an attempt to apply security. Where are the government agencies who are setting standards for the public schools as far computer/network security? How can this crap even happen? Even if this teacher tried to surf porn on purpose from a school computer she should not have been allowed to. If she can there is a failure in the system and the school should hold more liability than the teacher in my opinion. You want to "protect our children" then fix your freaking system!!
