Reply #48: No, the methodology is NOT "sound."

They sampled people who were shot, found out that they were more likely to be carrying than the national average, then announce "Carrying a gun makes you get shot." That's a grade-A logical fallacy. Particularly when you consider they're not distinguishing between legal and illegal carriage.

If you analyzed shootings in, say, inner city Baltimore you'd find that they're disproportionately young black guys, but that's not a basis for claiming that being a young black man causes you to be shot. It's because those kids are the ones getting dragged into gangs and gang warfare.

Looking at only cases where someone has been shot is called adverse selection: they're choosing a pool of people who are by definition not representative of the national average.
