What you "think" is unsupported by empirical evidence or objective fact, and is hardly the basis for policy or legislative measures, although there's plenty of people out there in legislatures across the nation who don't realize that.
This is just a retread of the same old anti-gun mantra saying that if people are allowed to defend themselves with guns, there'll be shootings over parking spaces and fender benders.
Every time a new state loosens its concealed carry restrictions, that same drum is hauled out and beaten as loudly as possible, and every time it's proven wrong in succeeding years.
Violent, confrontational crime went down markedly in Florida after 1987, and today you're more likely to be attacked by an alligator in Florida than a CCW licensee.
Vermont has had no state-level gun control, and no license to carry openly or concealed, since the early 1900's, and consistently has the lowest or second-lowest violent crime rate in the nation. New Hampshire has had shall-issue concealed carry since the 1920's, and competes with Vermont for the lowest crime rate in the nation.
If there was more likelihood of shootings erupting, you'd think that Vermont and New Hampshire would dominate the national crime rankings, but instead it's New York City, DC, and Chicago, where guns are all but banned, that take the lead.
And consider this: shootings don't just "erupt" as though they're a phenomenon of nature like Mt. St. Helens. They involve a specific act of will and volition on the part of the person involved. It's inappropriate to use that word, any more than it would be appropriate to say that this post "erupted" from my keyboard.
I’m definitely for non-felons carrying where ever and when ever they want but there is probably a better reason for Vermont and New Hamphsire having so little violent crime. It’s very un-PC to mention it, but they are probably the whitest states in the union (96%). Blacks are 1% in NH and less than that in VT. Add in another low crime group like Asians (1-2%) and you end up with a population coming almost entirely from low crime groups. The sad tragedy that is young black male crime just doesn’t hit those two states.
