If someone has a car accident and runs over my fence and into my yard, I consider that an unfortunate accidental trespass. That actually happened to my yard and fence, and I didn’t do anything about it. I told the drunk neighbor not to worry about it too much.
However, if someone comes into my house to steal and rob or to trash my house, then I think that “life in prison” is not too much of a punishment. (I’d probably let the guy out in 10 to 20 years anyway, but I would not let him know that at the start.)
If someone gets into my computer by some fluke or accident, I can live with that, but if someone hacks it on purpose to steal info or to trash it, I would like to see him get “life”. Ten or 20 years from now, we can consider giving him a pardon.
Perhaps you mean in twenty years, give him parole.
I just don't agree. I see computer intrusion as a criminal trespass. I don't think people who trespass should be given life in prison.
