I know someone who is currently going through a divorce, and it isn't pretty - although I doubt there are very many divorces without some sort of legal complication or emotional bitterness. One thing that my friend hasn't had to deal with is wiretapping, which is the gist of this news story: "Police blotter: Husband spies on wife's computer."
According to the story, "After her husband [Peter Garfinkel, 41] started court proceedings for a divorce, Lori Garfinkel  filed a counterclaim alleging the following: transmission of sexual disease, negligent infliction of emotional distress, intentional infliction of emotional distress, and wiretapping... Peter [admittedly] used an unspecified monitoring device to track his wife's computer transactions and record her e-mails. Lori was granted $7,500 on the wiretapping claim."
This wasn't the end of the court case, but you'll have to read the story to see what happened next. I know, sometimes I can be a real charm. :-)
Wiretapping is never cool, especially if you're the person being tapped! However, wiretapping apps and software continue to be consumed by the paranoid public - and the marketing for these products only proves this point: "Makers of key loggers (hardware or software methods of recording keystrokes) are actively marketing their products as ways to expose spousal wrongdoing. KeyGhost's Web site mentions 'multimillion-dollar divorce settlements,' and the description of BlazingTools Sofware's Perfect Keylogger includes this line: 'Are you wondering if your mate is planning a divorce?'" Personally, I think these products are equally as bad as checking your spouses e-mail (because he or she always uses the same password for everything). If you don't trust your partner, it's time to get out of the relationship!
