OK, I'll elaborate (slightly). Someone called for help, I answered the call. It was a similar situation to what rfurt encountered, except the result was much more permanent. The "victim" then proceeded to try and sue me, her attacker's family did sue, by the time it was over, I was financially and emotionally wiped out.
I hate to say it rfurt, but I'm willing to bet that the woman in your case, if she's not already, wil be screwing the miscreant again real soon. Trust me, it's not worth the bother. Stick to protecting you and yours.
By the way, nice Peacekeeper. Always wanted one.
