NYC has used analytics since 1993 and it's widely credited as contributing to the incredible drop in crime.I see the "NYC did X in the 90s and it caused crime to decrease" thing pretty often, but from what I've read, the real reasons for crime reduction in NYC aren't well understood, and when compared with crime reduction on the national level, NYC isn't really all that special; crime was dropping at similar rates throughout the country (and the world, even). So I'm not convinced that a NYC-centric examination of policy is at all representative. Not to mention that NYC itself is not a representative place, so what works in NYC may have no connection to what works elsewhere.
> Certainly we can decrease brutality by sending police into areas with no conflicts but that defeats the whole purpose of policing.
That's not the issue. The issue is that police are being sent to places, and because the computer told them to expect crime, they are primed to find crime, even if it's stuff they wouldn't bother with under normal circumstances. The simple act of saying "this neighborhood is a hot spot" makes it a hot spot, regardless of whether or not it actually is.
Put another way: the computer sends the police to places where there probably are some problems, but much fewer than police are primed to expect, so they end up creating problems in addition to any they solve. They get this "warzone" mentality where they feel like they're going into an "us vs. them" situation, where anyone on the street is assumed to possibly be a criminal. That's a recipe for unnecessary violence.
> We need effective and aggressive law enforcement as much as ever.
Effective, yes. We severely lack this in many places and need to work hard to fix this. Aggressive, no. That's why we're in the position we're in: aggressive assholes on a power trip who just happen to also be racist and think they're above the law.
> ...and show them that bad behavior will be punished severely.
That attitude suggests that you aren't really interested in making society better, just that you want to punish people for doing the wrong thing. But I suppose this shouldn't surprise me; based on incarceration rates and the state of prisons in the US, it doesn't seem like anyone is interested in prevention and rehabilitation, just "sticking it to those bad people".
