Or perhaps more to the point regarding weapons; If you are not willing to use it, do not carry it. Besides, know thyself, the human body is quite lethal and vulnerable both. But, all things considered it certainly is easier and more agreeable to never find oneself in such a disagreeable situation in the first place, as such I feel that stressing keeping yourself safe, aware and not doing foolish things should never be underestimated. Granted I probably take the thought to the extreme but I have never been able to justify going into a bar for instance, or any other place where incidents have happened or have reputed to have happened in the past.
Perhaps it is telling that I have only had problems when in situations I did not want to be in in the first place? (I.e. school, actually but *shrug*)
Anyway, just a few thoughts in the wind.
