Audio problem: Scully asks the deputy if the vests are necessary and he replies in the same scene. His mouth is way off from his reply. It's likely this is because the show was shown on 4:3 aspect ratio televisions at the time, and he would simply not be visible. Because the show was shot in 16:9, he is very much visible on modern televisions and the mistake is incredibly obvious.
