Currently you need to be a approved member to read any RT ticket. While I can understand that some tickets might need some secrecy, currently it's impossible for "normal people" to read tickets, or even find if a request has ever been made (well, not doing the full NSA though).
I think any ticket that hasn't been marked as secret, should be publicly traceable without the need for a login to access the information.
