Given the recent shootings of officers, the usual folks are on the media discussing prevention of gun violence. Usually, it turns to gun control measures. IMHO, I hear little about deterring people from carrying firearms for bad purposes.
So from a psych feed, here's an interesting take on the UK trying to prevent knife carrying. They have an increase in knife carrying and crime - which suggests the forces driving the recent crime increases in the world are more than simple access to weapons. The study looks at the messaging designed to deter weapons carrying (knives in this case) in the UK. Fear, responsibility to society messaging was attempted experimentally. These message were based on those that authorities had been using and based on various theories.
The bottom line is that none of the various messages had an effect on whether the participants would carry a knife.

Fear Appeals in Anti-Knife Carrying Campaigns: Successful or Counter-Productive?
I wonder if this is relevant to trying to prevent gun crimes in the USA. Is our messaging ineffective for the same reasons. Just something for those who like to read academic pieces.
