I was wondering why Whoopie never changed her outfit. But then it dawned on me, since Whoopie is a robot, I'm assuming that her Black widow outfit is her whole body. Like in her entirety is comprised of metal,plastics and internal noodle combustion. So in essence, she would not likely smell like a regular human being which would be a dead giveaway to dinosaurs. I'm thinking these dinosaurs would have enhanced smell receptors since they are primarily predator-like. It would defeat the purpose of trying to disguise yourself since it looks like robots are primarily in the police force to stop any dinosaur related criminal activity.
It would make sense to put robots for that type of activity since they would have Augmented strength to counteract Dinosaur strength. I don't think all police in this universe are robots, but there are specially made police robots who handle dinosaurs. or with the more logical conclusion, that the filming took place in an afternoon and she just went between sets and did her lines
