zombieslayer,
Unfortunately, I cannot say that given today's tilt towards the left that we are witnessing in our society as a whole but, in particular, in our judicial system that you are incorrect regarding the 'potential' negative ramifications of carrying additional ammo though there are many variables that will come into play. Also, you are clear that you do not have a problem with it etc. So I see your perspective as a valid point.
Yet my concern (on a macro-level) is that not only our country but the world as we know it (particularly relative to the fragile financial state of the entire international community which means what happens 'there' immediately has adverse effects here) is on the precipice of social chaos (we already see significant examples of such).
On a more micro-like level and in my neighborhood, for example, there are constant/perpetual "social" problems increasingly involving so called "flash mobs" whereby individuals are simultaneously attacked by 10's of people.
I was going to post some links but we can all youtube this stuff ourselves if vivid illustrations are necessary. So while I agree with your concern, I have chosen to carry an extra mag or two or a BUG just to be sure because I refuse to be the next victim of a group-thug-like attack.
-Cheers
