Look, if your argument for "nobody should ever trust anybody ever" is

[conuly]

"Something bad happened to somebody once, and when she ran to a stranger for help, she got raped" then at the very least you're going to have to give me this person's name or a link to the news story or something. Normally I'd say that thing about anecdotes and data, but without any identifying information this isn't even an anecdote.

Also, even if that story is 100% true as reported and actually happened to an actual person, never trusting anybody ever is still a very unhealthy way to live. I don't think the cost:benefit ratio actually adds up.
