The best way to alleviate the obesity "public health" crisis is to remove obesity from the realm of public health. It doesn't belong there. It's difficult to think of anything more private and of less public concern than what we choose to put into our bodies. It only becomes a public matter when we force the public to pay for the consequences of those choices.

We'll all make better choices about diet, exercise, and personal health when someone else isn't paying for the consequences of those choices.

Multiple studies, including from the Justice Department, have shown that the guns used in homicides, including the killing of police officers, overwhelmingly tend to be small-caliber handguns. Moreover, gun ownership has increased over the past 20 years — the same period in which both the violent crime rate and the killing of police officers have been in decline.

No one made a decision to militarize the police in America. The change has come slowly, the result of a generation of politicians and public officials fanning and exploiting public fears by declaring war on abstractions like crime, drug use, and terrorism. The resulting policies have made those war metaphors increasingly real.

Police officers today are a protected class, one no politician wants to oppose. Law enforcement interests may occasionally come up short on budgetary issues, but legislatures rarely if ever pass new laws to hold police more accountable, to restrict their powers, or to make them more transparent. In short, police today embody all of the threats the Founders feared were posed by standing armies, plus a few additional ones they couldn't have anticipated.

Finally, this case should serve as yet another reminder of just how dangerous and volatile these police home invasions really are, and why we should stop using them to serve search warrants for nonviolent crimes. They offer no margin for error.
