The clip I saw was Rick and Darryl clearing out the area of a bunch of silos, with Herscel staying in the truck armed with a M-4. The meeting when it does take place between the governor and Rick seems to be taking palce on nuetral ground.
You can always nit pick episodes but consider this. That walker loaded bar is only at best two blocks from where Morgan lives. Given all of the walker traps he has build he would to have cleared all local building out for materials or had at least went into a eating establishment to search for food.
That was a different arms locker than what was in the pilot. Why leave the high powered stuff the first time? No extra vests lying around? Seems like between the prison and the police station there would be more kevlar.
Crazy Rick dropped the ball. Chasing the White Rabbit, he left his birdseye perch and his binoculars. He would have saw the Governor and could have even stopped that ice cream truck with his .223 with some shots in the windshield.
