There is no mis-perception of crime

There is more knowledge of crime and the cost of crime.

Visualizing America's Crime Rate Perception Gap

The poster has seriously erred. What the survey responders are seeing are in the murder rates across the world:

List of cities by murder rate

 That is the picture that is becoming more accurate to the average person as time passes, and this author falls into their Euler trap of thinking we never reset our belief scale.

The list tells us that Mexico occupies half of the top twelve. Then we see St Louis before we see another Central American city.  Then Mexico, the USA and one more central American city arrive.

The worst on record is Tijuana, San Diego's suburb, and San Diego is a major port of exit and entry everywhere well known. The crime rate is rationally magnified when these facts are included.

If you show crime rates dropping, the responder is also seeing crime prevention costs rising, especially pensions and the growth of the public sector.  That is crime, crimes prevented is still crime and that is going up. The LA teachers strike was mostly about crime prevention, pay more to keep the statistics down.

We have not even added the Brazilian murder cases before we hit Europe.  Europe is sensible, they get all their murders done in one batch, tens of millions at a time.

But this author commits a serious error, these are not the same people, as Kling says.
