Me, too. In their world, strength in numbers is important, but you also have to plan for the eventuality that one or more of the people in your group will get infected/turn into a Walker. The people on the show seem to have grown complacent IMO.
Especially if you don’t have to get bit by a walker to turn into one.
If Herschel having a heart attack or someone else dying of an embolism can turn them into a walker, you should do a head count every day or even morning and night to identify the newly dead to dispatch.
They've done it repeatedly: when they were overrun before the farm, when they were overrun at the farm and now at the prison. The lessons just don't stick with these people.
And why would you be unarmed - ever! - under these circumstances?
