Most cities won't send out a cop to deal with that unless they don't have anything else to do or someone's been shot. Listen to the LA 911 dispatchers sometime.
Even if they dispatch immediately, it could be more than 30 minutes before they get there. Even under optimal conditions, the goblin has at least 5-8 minutes to do what he will with you.
Rape followed by murder takes all of 4 minutes.
Let me clarify my reply ... I did not at all mean to tell Dasher that she should not get both a gun and a cell phone. I think that both are handy tools for any woman. I simply think that she should also report it to the police, just on general principles. You never know; it might be a slow night when you call and something might actually get done. In any case, no harm is caused by reporting something like that, even if the cops aren't interested.
