Carrying around a firearm for the average person is silly. You are better off avoiding areas with a higher statistical probability of violent crime. If you live in a quiet neighborhood and stick around quiet friends you should be alright. On the other hand if you rub elbows with thugs and hoodrats, kill at will.
Sure, there are the occasional mall shootings and what not, but what are the odds that you will be a victim to this type of violence?
The best thing you can do is keep your head under the radar. I know that for big guys like myself and Ben, that is a difficult proposition, but it has to do more with posturing rather than appearance.
Those gun pron mags sure do have a bunch of entertaining albeit poorly written stories submitted by hillbillies and wannabe cowboys.
