Again, Switzerland. Kennesaw too. People are required to have assault weapons, and they are trustworthy. I'd also say I'm a very trustworthy person. Don't worry, I'm not gonna insinuate something stupid like 'if you disagree you're dishonoring me' or whatever. I've observed that the people I know who own guns are more polite and respectful in word and deed than the ones who don't: they're strong and emotionally secure individuals who look to themselves for faults before others.
And again, that Harvard Law study. The stats, when properly understood, show domestically that, when governments sanction and legitimize the bearing of weapons, greater peace lives in society.
Ignoring that, I don't see how this logic is disagreeable: A gov't naturally will either have to not do wildly unpopular things, or try to take the weapons away, or try to run PR so hard it turns into propaganda. Furthermore, an armed populace naturally means they will feel more culturally empowered, and there would likely be more watchdog etc. groups.
Lastly, a culture where people have killing power in their hands will create stronger community bonds because people will more likely be forced to respect each other and get along--and not in a morbid way. People who would get along anyways would, it's just that people who might do something stupid would be far more reticent to do so, and the people who do go through with stupidity would be dealt with far more equitably and efficiently than how the police (an inherently reactionary rather than preventative force) would. Mind, I don't mean absolutely. There will be cultures which aren't suited to this, but given that humans in general fall within general patterns of acting, I'd say this is generally accurate.
