What was the "complaint"? Per the testimonies of Curley and (presumably) Raykovitz, Curley only told Raykovitz that it was merely horseplay, that Penn State had already investigated the incident, and that there wasn't any more to be done. My guess as to why Raykovitz wasn't charged is because the state believes - both through Curley's and Raykovitz's testimonies - that Curley didn't tell Raykovitz that anything occurred that would need to be reported. The state is arguing that Curley lied to and misled Raykovitz into believing that the incident was horseplay, that PSU looked into it and that nothing more needed to be done. Now, the accuracy of all that is still yet to be determined, of course - but that's why I believe Raykovitz wasn't charged.
