Gun restrictions for citizens not only tends to reduce gun violence (apparently) but it also tends to reduce liberty.
I say take the guns away from one and all - police, military and citizens. Then, gun deaths will be nearly zero and the original purpose of the 2nd amendment will be fulfilled in that the gov will not have the balance of power in their favor by virtue of their own arms being able to over power a determined citizenry.
But the sudden uptick in blunt force trauma, sharp object and other deaths will leave more questions to be answered. At least those take more effort to accomplish but there's no good way to stop all highly motivated would-be murderers.
