Portugal is one of the most peaceful in the world (murder rate 0.7), 118 incarcerations per 100k, and doesn't have license plate readers or mass surveillance.
USA murder rate is 6.3, 541 incarcerations per 100k, extremely high recidivism, and an amazing array of surveillance systems.
Portugal decriminalized all drugs in 2001. Guess they should have bought Flock cameras instead?
Andorra and Finland both meet your four criteria.
Woodmore, Maryland is 82% black. Chance of being a victim of a violent crime is 1 in 904. That's three times safer than the national average. It's an extremely safe community with an overwhelming majority of residents being black.
Woodmore is a gated community so obviously it has an unrepresentative population.
It feels good and easy to say lock the bad people up. But the numbers don't show that as a solution if the real issue you're trying to solve is decrease violent crime.
Both Ghana and Sierra Leone are gated communities, just as the USofA, the UK, and Australia are.
I'd suggest that Woodmore fails to meet you particular bias, hence you rule it out.
Woodmore likely meets your four intended criteria depending upon the level of internal surveillance .. I suspect it's not surveillance that prevents Woodmore occupants from killing each other.
I said 74.
74?! That's way to many mouse traps. No one would ever need that many mouse traps.
But sir, I haven't told you how many mice I have.
The number of incarcerated individuals is not a relevant statistic if you're also not including the number of criminals there are.
If your 74 traps solve your problem and in a month you have no more mice, then congratulations.
But it sounds like rather than buying more and more mouse traps, you should find and fix the underlying cause.
Look at places and countries with low crime. They don't have the most Flock cameras, the most prisoners, or the most powerful surveillance evidence because while those may solve a crime, they don't solve crime as a whole.
