There's a new show on Nat Geo Wild called "Philadelphia Undercover." It's about the undercover unit of the Philly SPCA. The first 2 episodes covered a huge dog fighting ring bust, and it was quite intense. I really like the show so far. What a tough, tough job. These guys (and 1 gal) get threatened constantly and work in some seriously shady neighborhoods.
I don't understand how this unit is going to continue undercover work now that this show is on, but that's not my problem.
