You cannot give human infants cows' milk without them getting very sick. So the cows' milk given by the FBI would have been useless to the babies. However, the word "babies" in this context does not necessarily refer to literal infants; "baby" or "babies" is commonly used as a term of affection by rural Texas women with a traditional upbringing to refer to their children and those of their family and close friends.
When Gary Noesner pulls over to talk to Balenda Thibodeau, his front license plate is white with black letters and is marked with the year. Texas stopped issuing annual license plates in 1974 and began using annual registration stickers applied to the rear plate only. From 1986 to 1993, civilian plates had dark blue license letters with "TEXAS" in red or blue; only a few older private vehicles still had the 1975-1985 black-on-white plates by 1993. Police and government license plates retained the old black-and-white color scheme for several years longer, but they had the word "EXEMPT" under the word "TEXAS", and they were never marked with the year.
