There's really no way to get caught doing something like this if you're on the same LAN as everyone else as long as your computer's name isn't anything that personally identifies you. I'd do it in the bathroom though considering the fact that cameras + network traffic timestamps can get you caught.

This is so far from the truth it isn't even funny. Do you think that switches and routers don't look at your traffic in an attempt to manage them? In fact, it's so difficult to turn that feature off that many netadmin's don't even bother. At the end of the day, you're pretty easy to track down, but unless you're successful in doing something actually important (like robbing a bank), nobody cares enough about you (understandably so) to bother to look what you've done.
