There's a massive difference between taking special precautions while "casually strolling into a slum known for its violence" and being expected to take special precautions everywhere you go all of the time.
Even in the case where someone's freedom to wear a nice watch out in public is threatened by lawlessness steps should be taken to secure the ability for men to walk those streets without fear of being assaulted and robbed. Similarly, a woman's ability to dress herself how she likes should also be protected. If a place exists where someone should reasonably expect watches to be stolen or women to be assaulted that shows a failure of law enforcement. If you want to apportion blame the order is: criminals > law enforcement > victim
