Of course the first comment in the thread (and the only one, so far) is this:
For so long as the states which have "restrictive" firearms laws are surrounded by states with less strict laws, illegal or illegally obtained firearms will flow in to that state with the stricter laws. It's economics, stupid. And, for so long as that situation obtains, the NRA, the gunzmakerz and their useful idiots will conspire to ratchet up the fears of a burgeoning police state and simultaneous breakdown of law'n'order which situation requires that all merKKKins be armed, all of the time.
** And, yes, you ARE a criminal if you traffic in illegal weapons or traffic illegally in any weapons.
"Regardless of changes in the law, voters in the three states don’t think future mass shootings can be stopped by laws. Two-thirds of likely voters in Colorado, 60 percent in the Old Dominion and 57 percent in Wisconsin don’t think stricter laws can stop future attacks.""
