Am I going to jail for what I am writing in my book?

First off you think you are important enough that anyone is going to want this book? Really? My guess is that this is a bunch of BS anyway. Next if you REALLY cared about it then you should have gone to the police and offered to work for them. Even teach them how to go after the pervs, oh wait they probably already were doing it LEGALLY instead. You admit to breaking the law. Although any smart law enforcement officer would have locked their net connection(I'm not even in law and I know you should lock a wi-fi, which isn't to say that hackers don't get through pwords, but most don't bother). So let's see you'd be admitting to theft of internet services/leeching/whatever they call it there(it's illegal to use someone else's wi-fi without their permission), hacking, and who knows what with what you did online. You say this law enforcement officer has it in for you and wants to bring you down. Yeah you'd be caught red-handed, this would simply be a confession. Heck this on here is basically a confession to illegal acts if the police read it an believe you are serious.
