Inspired by Tor - Think!

So, inspired by the recent Tor story (this and many others), here is something to think about:

1. You buy a PC and connect to Internet (pay for your own connection)
   
2. Download and install Tor
3. Monitor it (full packet cap) in violation of its license, but in compliance with your policy
   
4. See what looks like a secret email from somebody
   
5. Grab the email and send it to a journalist
6. Ooops! :-)
   

So, the question is: is this legal? can you be sued regardless? would you do it?

P.S. similar discussion kinda occurred on the Honeynet Project internal list about a year ago and the results were ... well, inconclusive at best.
