The Walking Dead Season 6 Official trailer

My prediction: Rick thinks the community needs to train, that everyone needs to be able to fight. He starts taking Alexandrians on runs, a few die, people get pissed off at him and start second guessing him. Massive herd comes, knocks down the wall, lots of people die, Rick is proved right. PS Why are the diagonal supports for the wall on the outside not the inside where the could oppose the push of a herd.
