City-wide statistics seem almost entirely meaningless in these contexts. Most violent crime is concentrated in specific parts of the city where the people who participate in these debates never go. A 10% decrease in violent crime in the most dangerous part of a city could cancel out a 10x increase in the areas where most HN people would likely be living in.

Don't forget, there's different kinds of crimes with different visibilities.

So there could be a 50% decrease in violent crime in the most dangerous part of a city, along with a 500% increase in non-violent or petty crimes everywhere else: shoplifting, parked car smash-and-grabs, urinating in the train stations, pooping on the sidewalks, etc. So the tech crowd isn't going to notice fewer people getting murdered in the worst section of town, but they'll definitely see the other stuff.

I can't tell what point you are trying to make. Are you suggesting that while crime overall is down, this new situation is actually worse because the victims are now likely to have more money than past victims?
