People need heuristics to determine
wether a person in the street is a possible
threat or not.
I just read an article with somebody
complaining that people still often use
skincolor and other racism as a heuristic.
While he (and many like him) had
absolutely nothing to do with people
his skincolor who end up high in crime
statistics and are structurally connected to
crime in the mass media.
My experience is that it is totally
unreliable and just plain unhuman to
judge someone on the color of their skin.
I propose a much more reliable heuristic.
The shoes people wear.
Make a photobook with pictures looking
down on the feet of criminals, showing
what shoes they wear. In the corner of the
picture the crime history and all relevant
data of the person is listed.
Not only street criminals, but also financial
frauds and all that.
