Is it racist, is it sexist or is it both? And is getting the man more important then protecting the public?

In the book people are looking at the racist aspect and not the sexist one, in chapter 11 the factors of this come forward as well as the aspects why weren't police warning and protecting the public. A passage on page 122 tell the story of the sexist part of what happens in the book.

"The police are statutory obligated to prevent crime, and, at common law, they owe a duty to protect life and property. The police force failed utterly in their duty to protect the plaintiff and other victims from a serial rapist know to be in their midst by failing to warn them so that they might have had the opportunity to take steps to protect themselves... The conduct of the investigation and, in particular, the failure to warn was motived and informed by the adherence to rape myths as well as sexist stereotypical reasoning about rape, about women, and about women who were raped..." pg. 122

Chapter 11 is all about how police failed to protect Theresa Kematch from getting raped and it gave an example of another time were police did not warn women of a rapist in the area even though they knew there was a serial rapist in the area and how he was committing his crimes. In both these example the police failed to warn and protect women because they were afraid that the criminal would flee.
So there are several factor that come in to play in Crawford's case: public safety, sexist and racist factors as well.
 I want to know is it more important to police to get the man the to protect the public, I do understand by getting the man the police are protecting the public by getting him off the street but is it still right when they basically see a women get raped or they know it will happen again and they are not warning people. What is the priority of the police?
As it was said in the book "had she been a white women, would the police have permitted John Crawford to take her to such a place and subject her to potential danger?" pg. 120 This is a deep question but I don't know the answer to this if they would interfere if it was a "white" women it is a racial aspect but if they would't it would be a sexist factor. (Did anyone wonder if it was a man being raped would they interfere would things have gone fast and would it get more coverage. (has actually happen but the guy that actual killed his victims too)) The fact of it is rapist aren't on media often and they aren't really talked about them even if they murder, it doesn't seem like a priority.
The fact is that there is a racist factor for media but when it came to the police is it also a sexist or did they do what they did to be able to get their man fast to protect women in the long run even though they might have allowed a few women to have a bad experience. there is no real answer in the book for these question but they are important ones.
