I've become extremely paranoid about my girlfriend getting raped on her trek home through the city during the night. She's 5'2 and has big tits and ass so I'm starting think its just a matter of time considering I live in Eugene. And even when I'm with her I worry because I'm kind of a pussy.

So I'm here to ask for suggestions.

Should we get a gun?
Pepper spray?
Tazer?
Quit letting her walk the streets
Make her really unfuckable?
