I've already been in three (possibly more, if it comes to that) incidents where I've been the victim of physical assault. So at any rate I'm not speaking from a position of total naivety. In all cases I still would stand be the statement that having a gun wouldn't have made me any safer. Indeed, it might have been the opposite. I'm relatively timid anyway, so unless they were frightened off by the mere sight of the weapon (which is always a possibility) a likely scenario would be that they grabbed the gun off me and turned it on me. That, or they ended up dead. So, a situation which ended with a certain amount of psychological damage already could well have ended up with the same, plus perhaps one or more dead bodies. We'll never know, of course, but I'm unconvinced that it would have led to any changes for the better. And for that matter, any situation in which I had access to a gun, the people attacking me would have had the same amount of access and probably rather more inclination to get one, too...
In response to your statistics, that's an impressive rate of reduction caused by concealed carry, but surely it's overlooking the fact that the gun-related homicide rates in the US are vastly out of proportion with the population size compared to a country with strict gun control laws. An 8% reduction is all well and good, but it's still far too many and looks rather like an attempt to justify a position by pretending that it's OK to have disproportionately high murder rates so long as you are safer. When presented like that, how can the position make any sense? You have to be less safe to be more safe?! It does seem rather like that. For comparison, gun-related murder rates in the UK are something in the region of 40 times lower than in the US (says this source:

There are at least some gun advocates in the US who do go on about protecting themselves from the government. To be fair, I don't know how representative or not they are of the general population. Certainly they can be more vocal. One of them shouted rather loudly at Piers Morgan in an "interview" that got a great deal of coverage, and I don't think he's the only one who makes that point -- indeed, your dark reference to 1930s German policy is somewhat similar in message of not in tone. To the best of my knowledge, by contrast, the UK has both some of the tightest gun control laws in the world but also some of the least problems with military dictatorship, and frankly the UK of today is a far better comparison with what would follow any gun control push than the Germany of yesteryear, so any form of argument that "they can take our guns, and then they'll take our freedom" is surely teetering on the edge of paranoia.
I feel safer without a gun, personally. I can just about understand why someone would feel safer with one, but in practice it's an illusion. You become more dangerous to yourself with a gun, and more dangerous to others too. This should be reasonably obvious, I'd have thought -- the margins for error are far, far slimmer with a gun than without. We've seen far too many accidental gun deaths in the US. Says one source, 3,800 accidental deaths in the US in a period of five years, or a little over two a day. That's also 3,800 too many.

It is, as far as I can see, clear that gun ownership in general leads to people being less safe, not more, and the solution should surely therefore be to work to reduce the number of guns around, rather than to increase it.
