Holy crap what a sucky way to go <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />
The irony is that if it happened in my city or any number of European countries, and a person HAD a knife and cut her free, they would likely face charges for carrying a deadly weapon.
Still, ridiculous that no-one had a knife or people didn't want to help. I always carry at least a couple of knives (usually a keychain knife and a bigger knife so I have a choice depending on the situation), and I have a FAK with EMT shears in my work bag.
