The grain of salt to add is that rates are dependent on reporting, just like rates of a disease are dependent on diagnosis.

In my part of the US, the rate of “burglar bars” on windows have slowly gone down and I see no uptick. This leads me to give credence the “crime down” hypothesis based on people’s behavior at scale.

On the other hand I see more preparation for civil disaster and disorder. Firearms may be more part of that story than a reflection of people’s thoughts about the potential for victimization during a “normal” day.
