Does anyone know why MAP focuses on the clearance rate? It seems to conflate
arresting someone with "solving" the murder.

I can think of some plausible reasons: practicality (easiest to collect,
stable over time), political (if your audience is the police, basing your work
on the assumption that they arrest the right guy is probably smart),
standardization (is it?), etc.

Wikipedia is fairly light, but does link to a pair of articles on the criminal
justice conflict vs consensus models, so it seems this is a potential can of
worms.

I'm really not moved by the "resources" argument all the PDs are giving.

Investigating murders is the kind of thing you do when you've run out of meth
labs to bust and black guys to beat. It's a high effort, low reward task. Of
course they'd much rather cut back there than not buy everyone tazers.

The article title "Serial Killers Should Fear This Algorithm" is naive since
psychopaths do not feel emotions like fear or empathy, or at least not
spontaneously.[1]

I've tried to test a psychopath in the wild using a word association
psychoanalysis method[2], but they are hard to find. Hospitals would not
divulge names (no surprise there) and many psychopaths are senior corporate
professionals who run successful companies.[3]

A serial killer who strangles women is probably a "Lust Killer" and not a
psychopath.

> a "Lust Killer" and not a psychopath

are these exclusive notions?

I feel like you build a model which you implement in software. (which runs on
hardware)

cynical me thinks it simply isn't profitable to them to solve murder cases
unless public outcry is very high and more profitable to beat on the fear of
drugs and perform seizures.

post 2010 drop could unfortunately be attributed to a hostile media and
Presidency towards the police because of some overly politicized cases

Definitely there's been a reduction in trust between police departments &
citizens, but I'm not sure I agree with you whose _fault_ it is.
