For those calling for more gun control, I would observe that, since all laws are dependent on every citizen's willingness to cooperate and fulfill the law's obligation, there will always be limits to what laws may accomplish.
In the case in point, if the United States Air Force had done what they are supposed to do with the information they had on the latest atheist miscreant to vent his psychotic rage on a collection of Christians, given that he had spent a year in the brig for violence to women and children, not to mention a demonstrated fondness for unsavory computer materials, he would not have been permitted to purchase a firearm under existing gun control laws.
By all means, create more control laws, just don't fool yourselves into thinking that a greater complication of laws means greater compliance or the absence of bureaucratic folly.
If someone in public office, say a senator from my state, dusts off a pre-written statement on gun violence seemingly within minutes of an act of violence, I suspect merely to use wanton slaughter to raise his political profile, I would direct you to something I wrote earlier about the steps to take to repeal the Second Amendment. Whoever initiates this action will never be president, but it will make those pre-written statements seem less hollow.
Also, clergy colleagues, when has a scolding, know-it-all tone ever convinced anyone in this century that your political perspective is inviolate?
