I used to legally carry a concealed weapon (handgun) in California, so I'm not too happy about being generally categorized as a thug. I only had to draw my weapon 3x and never had to discharge the firearm - which made me extraordinarily happy as it's a tremendous amount of police paperwork to shoot someone - not to mention the prolific civil lawsuits.
I probably could have accomplished the same effect with a baseball bat - but I responsibly enjoyed the privilege of my firearms - although you are probably correct that an inordinate amount of civilian morons - to include law enforcement and military also irresponsibly possess and wield firearms.
Personally, I'm amazed at the kinds of seriously dangerous explosives one can purchase during fireworks festivals in China.
The general issue with firearms - isn't the firearms, but the lack of responsibility, training, and common sense - asking a government to ensure our safety from firearm wielding thugs has also never historically worked. Although firearms violations are rare in China - the recent Yunnan case and Chinese history in general shows a focused, single minded individual can accomplish what your seek to avoid through bans.
So the real issue is not wielding firearms, bludgeoning instruments, or even learning hand-to-hand martial arts (lots of morons are well educated in hand-to-hand combat also), but the ingrained training of social responsibility, compassion, and common sense - basically an educational issue - both at home, at school, and in society in general.
In the military - I've met an inordinate number of blacks with exceptional responsibility, respect, loyalty, etc. In public life - I've rarely met American blacks that I'd want my kids to know - that doesn't make me hate or discriminate against blacks - just makes me more cautious about people's backgrounds, personality, and behavioral traits.
As for firearms - the USA is the number 1 global exporter of weapons in the world - so banning weapons at home when we are a prolific global exporter is extraordinarily hypocritical (of the US gov) - in my personal opinion.
Regardless of our fundamental perspectives on an armed populace - you've had an incredibly dangerous, if not unique experience, both personally and with the unfortunate victims you've been acquainted with. A healthy dose of paranoia is definitely appropriate in your case - and thank you for reminding us all to be situationally and environmentally aware. I must admit - I'm considerably more relaxed in China than anywhere I travel in the USA.
Incidentally - those three cases I've had to draw my weapon - all racially motivated. Even in California - white and black americans don't seem particularly pleased about a Chinese American driving expensive cars - should I then drive something I don't like simply because I'm a target of violent envious racists?
I love America because of the freedom - but freedom comes with significantly increased responsibility - and we as Americans take a LOT of that freedom for granted and unfortunately, it's beginning to take its toll on our society.
And I might point out again - its significantly safer to stroll around virtually anywhere in Beijing - regardless of time of day - than to stroll around anywhere in Washington DC. I find that detestably shameful for us as a country. What happens in our capital cities is a reflection of our nation. The USA is a paramount for violent crime, rampant drug use, and a pervasive lack of ethics heavily dosed with prodigious selfishness and self-serving platitudes.
China - as evidenced by Beijing - seriously nasty environmental pollution. But Beijing has FINALLY elevated environmental pollution to public enemy number 1.
America? We have a chronic problem with violent crime - a social disease. Either way - I don't envy the government officials of either China OR the USA - tremendous responsibility with seemingly little public gratitude.
Regretfully, in our lifetimes, government of the people and of the state is still an experimental trial by error - we have a very very long way to go before our world and society in general is a harmonious place to live.
