The most fascinating thing to me is that the biggest indicator that you are going to be murdered is that you have been arrested in association with someone else who did get murdered. Police can address homicide rates by intervening in the lives of these future victims. When some low-level neighborhood criminal gets shot, go find all that guy's friends and offer them jobs in other cities.
That makes complete sense to me. Being involved in any sort of business where the underlying activity is criminal in nature means that contract disputes and even competition for market share have to be underwritten by violence and the willingness to resort to violence with no legal system to turn to for redress.
In the same way that being served with a lawsuit means likely to spending some time with lawyers or in court, a low-level criminal being shot indicates that his coworkers in the enterprise are likely to spend some time in shootouts.
They do this in Baltimore, it’s called GVRS. They find and assign risk scores (related to arrest but also some other stuff) and go seek out the person, offer them help or threaten to come down hard on them if they commit crimes
The pilot had a homicide reduction of 30% iirc but we will see over time as it expands to whole city how it plays out
