On set of the final 8

AMC released this - A video on the set of the final 8. I do not care that wiki says it has 0 views, but watch it while reading this, some of the cast say there will be plot twists, some major, do you think there will be MAJOR twists, like Jesse turning out to be a "Krazy 8" (Snitch)? I don't, but why would they say that?

And another thing: At a point in the video, we see Walt (Bryan Cranston) talking in front of a cop car, it is while they are filming, so... There will involve a cop car: What for?
