The problem is that people often confuse the concepts of legal/moral fault with poor planning. The woman who walks into Central Park at night wearing skimpy clothing and flashing a wad of cash has a perfect right to do so, and the Law should support her right against any rapists or muggers who claim otherwise -- this includes her right to defend herself from same. It is however a very bad plan, and I wouldn't advise anyone whose safety I cared about to actually do it.

The legal and moral fault, as always, lies with the criminal, not his victim.
