America isn't THAT big, and most people are never more than an hour or two from a state line unless they're in the middle of TX or something.
Although most people in Michigan do find themselves within just an hour or two of Ohio and Indiana, there are populous areas in Northern Lower Michgian and the UP that are anywhere from 4 to 6 hours from the nearest state line, and many wealthy people who might like to own a Tesla have homes up there. Michigan is entirely peninsulas (except for the islands, of course), and that has a funny way of physically isolating you from other states - maybe not as much as in huge states like Texas, but still.
Now if they could go pick up their shiny new Tesla in Canada, that would be something else....
A practical question for your brother - If he's approaching a scene where there is a gun battle between the hypothetical competent law-abiding citizen and the active shooter bad guy, how does he know which is which?
Well, he has two options then:
1) Let the firefight play out until he knows which party is the original aggressor (ie, the Bad Guy). If one party is victorious in the firefight but then continues to shoot non-combatants, then he knows who the Bad Guys are. However, if the victorious party stops shooting after the firefight, the police order them to the ground and sort out the situation, determining eventually that they're the Good Guys.
2) Shoot everyone with a gun. This is bad news for the legally armed person, but is a known and accepted risk among concealed carriers (source: I am one, and I know many who are; we understand we could be mistaken for bad guys in this kind of situation, and accept that risk if we choose to engage the Bad Guy).
Either situation is a happier outcome for the innocent noncombatants than just hunkering down and dying en masse until the police arrive.
Now, collateral damage is always more of a risk with more combatants, especially with concealed carriers who don't keep up on their tactical training. However, I suspect that the overall damage is still lower than just letting the killer keep shooting at defenseless people, especially since most people tend to either run or take cover when gun fire starts, meaning there won't be too many people in the line of fire for very long except in very crowded places, and so the overall casualties will still be lower.
Mint is an Ubuntu fork. And it is wonderful.
+1 to this. I actually switched my wife to Mint with Cinnamon from Mac OS. All the drivers worked without any tweaking. My wife's not technical at all, but had zero issues using the system and finds it very intuitive. She particularly likes the blend of clean aesthetics and great functionality - she's an artist, so I take her approval of the aesthetics quite seriously.
Real Programmers don't write in FORTRAN. FORTRAN is for pipe stress freaks and crystallography weenies. FORTRAN is for wimp engineers who wear white socks.
