One of the theories to explain the decrease in violent crime is the advent of violent/engaging electronic entertainment.
You see decreasing crime levels all around the Western world, with a few exceptions such as Brazil, Jamaica, and Mexico.
The decreasing levels of crime start in the mid 1990’s. They tend to level off for about a decade, then dropped some more after about 2008. There has been an uptic with the Ferguson effect and the attack on police.
I think the uptick seems to be in very specific communities.
I recall that supposedly some of the people drafted into WWI couldn’t pull the trigger. They had no way to get ready for what it would be like to point a gun at someone and shoot. Now almost everyone has played a shooting simulation, and has seen 1000’s of shootings portrayed in other media so the thinking goes they now wouldn’t have that problem.
