Re: More guns = safer for everyone
"Conversely, the least safe states and cities - such as Chicago - have extremely strict gun laws."
You very much can argue with cherry picked statistics. Correlation <> Causation
I would imagine that in genteel old New Hampshire, there was little gun crime anyway, compared to the mean streets of Chicago. I suspect they have tried to tighten gun control to cut the pre-existing problem.
Disclaimer: I am not a USAian, so not personally familiar with either place. Maybe outside popular TV and movies New Hampshire is really a hot bed of gang activity and Chicago is really a peaceful garden city populated entirely by retired lawyers tending their rose gardens.
