I noticed that too.I heard people yelling "let us out" when theey ran passed the Conexes, and at one point they ran passed a cage that had meat/bones all over the ground.

I was wondering why Rick was getting so excited about the chain hanging out of that guys pocket, then I realized it was the watch, and even when he was looking everyone over in the courtyard I noticed the guy with the body armor and knew they did something to the others that showed up earlier. I thought they were already died when I seen the bones.
I don't follow the comics but am still interested in the show to see what happens next. At least it's not a reality show like all the other networks are running all the time
