First of all, if I offended anyone or made light of their comments, I apologize.
Second of all, I NEVER said that I personally could not be taken by surprise. Yeah, it is Tactics and Training, and there are a lot of great ideas being exchanged on this forum, but I just can not live my life trying to account for every possible way in which someone may inflict harm on me or my loved ones. There is just no way to cover ALL the bases.
My point is that these "How do you defend yourself against..." scenarios are endless!
Let's take the same premise, but probably even more likely than being tased, how would you defend yourself if someone has a can of mace or pepper spray in hand pointed at you? It is a lot cheaper and a lot more readily available and a lot easier to use than a taser.
My other point is that regardless of how aware you are and how much you practice, there is always something you didn't count on.
On March 30, 1981, John Hinkley, Jr. managed to shoot President Reagan. 10 years later on On May 13, 1991, Mehmet Alì Agca shot Pope John Paul II. In both of these cases, these men were being protected by the most elite of all security teams on the face of the earth. There are no more thoroughly trained and situationally aware individuals than the US Secret Service and the Swiss Guard, (I am sure there are others, but these two are relevant to my statement) but yet, someone managed to get past them. If someone wants to get past your defenses, they will.
I guess what I am trying to say is that we can all be more aware of our surroundings. Carry a weapon (or weapons) and learn how to use them. Train diligently and seriously as if your life depended on it... because it does! But most of all, live your life to the fullest and don't live your life in fear. I don't.
