Now, from an intuitive standpoint, what Mr. Klapper did seems wrong, and I would like to think that the law provides some disincentives for behavior like that engaged in by Mr. Klapper. However, that's a relatively minor point, as there's lots of behavior that people may find objectionable that the law doesn't prohibit, or even frown upon. Indeed, from the decision in this case, it appears that Mr. Klapper's activities fall into that broad class of behavior, as the judge dismissed the charges against him as facially insufficient. What isn't a minor point is the reason given for dismissing the charges. According to Judge Whiten
In this day of wide dissemination of thoughts and messages through transmissions which are vulnerable to interception and readable by unintended parties, armed with software, spyware, viruses and cookies spreading capacity; the concept of internet privacy is a fallacy upon which no one should rely.
It is today's reality that a reasonable expectation of internet privacy is lost, upon your affirmative keystroke. Compound that reality with an employee's use of his or her employer's computer for the transmittal of non-business related messages, and the technological reality meets the legal roadway, which equals the exit of any reasonable expectation of, or right to, privacy in such communications.
I don't like the end result of the case, but the reasoning behind it is an abomination which should be stricken from the face of history. If anything that you type into a computer is considered to not be private (i.e., "a reasonable expectation of internet privacy is lost, upon your affirmative keystroke"), then everything I do, including work done for clients that I have asserted is covered by attorney-client privilege, is potentially public and could be considered fair game for anyone who wants to request it in litigation. This would be a complete surprise for me, and, I'm guessing every other practicing lawyer in the country.
In any case, I expect that the reasoning behind People v. Klapper is unlikely to be considered persuasive in many cases going forward. However, the fact that it appeared in even one case serves as a reminder that, when it comes to information privacy law, relying on even the most basic principles can be a dicey proposition.
