Whether or not it was intentional, there are a lot of witnesses (see Palamara's article) that speak of a drastic slowdown, near-stop, etc., and they are spread out all over Dealey Plaza. There aren't that many who speak of a full stop. It's hard to know just how hard the braking was. But it certainly looks more accentuated in Muchmore and Nix than in Zapruder -- FWIW.
