On the contrary, I was responding to what was said... and unlike you providing additional information and the suggestion that maybe things weren't as clear cut as was being said.
Try comparing murder rates between Europe where guns are hard to get and the U.S. where guns are easy to get. Comparing U.S. cities is just silly.
First... why is it silly? Why is it silly to recognize that gun violence is not uniformly distributed across the country and instead often seen in largest #'s in certain locations? If we follow your logic to other areas, it would seem that you'd claim that economies of all of Europe be balanced out on paper to judge their collective status without noting the relative differences between say... Germany and Greece?
It's plenty easy to say X==Y or even X=>Y, and often such assertions will be accepted. Often though it's good to examine the underlying environment to see if X=>Y, or if X+(A+B+C)=>Y while X-(A+B+C) !=> Y.
We let well-trained (in most cases) police and body guards carry weapons, unless you live in Texas where just about any yokel can arm up.
'We'? Who is 'we'? Where is 'we'? Here in the US, it's relatively straight forward to get a gun in most of the states, though some states (New Jersey being the biggest) and municipalities (Chicago, DC, etc) have additional restrictions on simply purchasing/owning something.
It's funny you mention carrying... while 3 states allow largely unrestricted concealed carrying of a pistol (ie no permit required), another 39 are 'shall issue' states, which means so long as you meet the requirements and are not otherwise prohibited, you get your permit. I know hating on Texas (a state I have never been to/in) is a favorite pastime on /., it's kind of funny you mentioning them as that while a shall issue state, they are one of only six that prohibits open carrying if a pistol.
Now that should make you feel real safe, eh?
Nope, I'm still waiting to hear about 'we'.
Now, let's make sure only the non-crazy people get those permits to carry a gun. How do you tell which are the crazy ones? You just have to ask them.
Now we see you straying into straw man territory, where in my original post did I discuss carrying a gun? *hint* I didn't, I only brought it up now in reply to you.
To my point above, in most states a permit is not required to carry a gun... provided it is visible. And what magic does a permit bestow on a person when carrying concealed? More often than not, you as a private individual cannot tell the difference between a person carrying and not... let alone if the person carrying has a permit to carry or not. This was part of why stop and frisk was so useful, the police were better at spotting such people and removing illegally carried guns from the streets of New York City.
More so, what on earth does 'asking them' have to do with telling 'which are the crazy ones'? I've known a few disturbed people who are pretty good actors and would not show up on your radar if you asked... but that is why we have other mechanisms to check ones background... if they opt to carry concealed legally.
