Likewise, thanks.
Laws affect all people, so you can't look at a specific situation to prove the rule.  Across the entire population, there is a 100% certainty that there are unintended consequences to owning a firearm.
That's a strawman argument, but it seems to come up often, so allow me to debunk it.  The natural use of any of those other items is non-injurious 
to anyone.  The natural use of a gun (and by use I mean firing it) is injurious.  
First, I still don't agree that "training taking over" is going to get you through this situation 100% of the time 
in the manner you intended (I found 
this interesting article that appears to support 
neither of our positions, or both - I can't tell).  The risks just aren't worth it in my house.
Second, the flaw with the "gun safety by training" arguments in this thread is that they focus on the top 10-20% (and I am being 
extremely generous with that guestimate) of the gun-owning population.  Given the amount of training that you have gone through and your background, I have no reason to doubt that you are a better marksman than the average police officer.  I would venture to guess that the gun-owners with which you associate are like-minded in their view of the importance of vigorous training.  
However, this argument ignores the fact that the vast majority of people who own guns do not take the time to get the training that you describe.  If this training were made mandatory, then I 
might be a 
little more comfortable with the idea.
