Burkes Seven lost his badge; thats why Burkes Seven was formed to catch the shooter of Moz and get an idea who is behind the music box and kates death.
Prisoners Dilemma helped a fellow FBI agent was kinda on run but didn't loose badge; stole a nice car with help of neal and love the sting in that one.
I think S3 was season he survived not having his badge taken away.
Be intresting to see what happens S4.
oh you're right, I got season one and two all mixed up. Burke Seven is season two of course. So anyway, yes, it doesn't sound good for Peter's badge. ^^
