It is not necessary for people to know the extent of criminal activity in order to be able to take precautions, everyone regardless of whether they know the amount of crime in an area should take what precautions against being attacked that they can. For example they should stick to walking on well-lit streets at night. Local groups on the other hand do not need to be informed by the newspapers if there is crime in the area, they will already know because they live there how safe the area is. The police will certainly give residents the information if there is a threat to them even if they are not giving that information to the media.
