I am a female who lives alone, most of the year, and I see no need to have a bloody taser. I can see myself now trying to wield one at three in the morning, no glasses on and stumbling around in my jammie jams half bloody asleep! With my luck all I would wind up doing is either tasering a gibnut or myself! Any weapon, even the ubiquitous machete, when presented will escalate a situation. That truism is law enforcement common sense. Do not produce a weapon unless u are gonna use it. Do not warn the mofos as to how bad-assed u are, u better be prepared to use it.
What difference does gender make anyway? With so many old drunk farts running around down here I would have to say that I am in much better shape to defend myself sans weapons than the average drunken old gringo could. No offence btw to drunken old gringos as I plan on being one about twenty years from now. (grin)
