Fwiw, I already live in a country/county/city/neighborhood where I don't "need to" (quotative, not quoting from in thread) fear crime daily. Discretion is a matter of personally choice that is determined based on a numbe of variables, and for me the activity I am engaging in is more important than whether I have a 1/10,000 or a 1/100,000 or a 1/10,000,000 chance of getting raped or murdered on any given night. Another consideration is general appropriateness, which is founded in cultural expectations more than concrete safety concerns. When our cultural expectations differ it is very easy to see another's perceived inappropriateness as a reason why something bad may have happened to another person. To wit, accidental deaths/suicide occurring in homes where there are guns present, or women who are raped while wearing short skirts.
Blame placed upon the victim is less blame for what happened than blame for violating our personal perception of the social norm or what it ought to be.
