Something that really bothers me is the disconnect between Deanna and Rick seems to have started as soon as she appointed him "law enforcement officer."
There seems to have been little discussion or understanding of what laws to enforce, and how to enforce them. This should have been a thorough process, because without it, there is tremendous potential for ambiguity and misunderstanding.
I'm not defending Rick, because as an experienced police officer he should know better how to de-escalate, and he obviously did the opposite. But his point was valid, and poorly addressed: The people of Alexandria had a known wife beater in their midst and did nothing about it?
When Pete asked Rick, "What are you going to do, put me in jail?" the answer should have been, "Yes, you'll be confined or separated if necessary." But Pete seemed to know that was not an option and that he was above the law.
Kind of a big confusing plot hole for me.
The Alexandrians seem to be on the level.
You sure Deanna and the Alexandria people aren't keeping some important knowledge from Rick and his group (and us)? The Alexandrians seem too weak to survive let alone thrive in this environment. I think they're hiding a big secret.
