In my opinion Red Cedar is a very nice neighborhood. I've shown many homes in Red Cedar. If you ask 10 different people that question you are going to get 10 different answers. You can try calling the Bristol Township Police Department directly & someone will give you the answers you are looking for with regards to crime & safety.
Your Realtor can provide crime statistics for a given area, plus, you can always drive by the neighborhood, assuming you are local to do so.
Outside of that, I suggest that you contact the local police department (there will be a non 911 number for general information) where the home you are intersted in is located. In Pennsylvania, most police departments are located in the same building as the township's municipality (exception is cities such as Philadelphia, etc.).
When you call, tell them you are interested in a home located on such and such street and ask them to provide information on the street and neighborhood. They may put you in touch with a police officer who handles these types of questions.
