Facts? there are little facts to support my claims other than my observations of his behavior to date.
And that's the very premise of how anti-gunners think. They take that reasoning and brainwash people into thinking it's "common sense" thinking.
As concerned you should be, the basic fact of the matter is no one should be allowed to be restricted to exercise their rights guaranteed under the 2A until a crime is committed. We're back to blaming the inanimate object instead of the person. If your neighbor commits a crime, then harsh punishment should be administered under a jury of his peers, not a ban on the firearm. The anti-gunners are using the very argument you pose for AR15s.
BTW, is the MK19 a full auto weapon?
