I do think this is kind of naive. If you consider something like a sexual assault, or even the more severe forms of harassment, that tends to happen among people who know each other, and people often don't talk about it after being victimized. So you not knowing those stories out of your tight knit community doesn't mean much -- if those stories exist you might need to have the parties involved trust you a lot to confide it, or you might need to really probe people about it.
