I suspect you're not a pretty girl that gets stared at. Neither am I, but if I were I'd rather the stares weren't recordable.
People generally commit less crime if they think they're on camera
If they do commit a crime, at least there would be video evidence
Or if they just want to be creepy, I'd send those stares to their wife
Considering motivated perverts would use hidden cameras, as opposed to cameras literally on their face, I think the asymmetry here is in favor of recording the perverts rather than vice versa
Unlike the sword, the camera itself does not incite deeds of violence
My understanding at least is that cameras (or even signs) reducing/preventing crime by _some_ amount has been independently corroborated across multiple studies
