Big Jim is the worst written villain of all time. Each time someone asks him something that can be easily explained away, he's gives the most roundabout answer. He's almost cartoonish, just missing the mustache to twirl.
So in order to keep him looking smart, Linda and the majority of Chester's Mill residents are made to look like idiots. Jim tells Linda to jump and she says how high. She worked beside Barbie and had him as a deputy for a bit and now she's taking Jim at his word that he killed all these people. What a one eighty. And the opening scene of last night reminds me of a MST3K joke about an "easy-led wise council." These people are such dullards.
This was all from the original book, where Big Jim was even more blatantly evil. He just said "Barbie did this" and everyone believed him.
