Rise in Crime (5 Year)

• Robbery

• Burglary

• Theft from MVs

Lack of Resources

• Reduced Manpower

• Increased Demand

• Shrinking Budgets

It is not uncommon at many police departments,

according to the National Alliance on Mental Illness,

for more than 20% of daily calls

for service to involve people who

are emotionally disturbed.

Mental illness cases swamp criminal justice system, Kevin Johnson, USA Today, 2014

“We have replaced the hospital bed with the jail cell, the homeless shelter and the coffin”

“Some are looking to the police department to do things that you never imagined. Dealing with the mentally ill is part of that.”

“Police should not be involved this process at all, but nobody else can or wants to do it.”

“Law enforcement did not ask for this additional challenge.”

They end up here (the criminal justice system), because we are the only system that can’t say no.”

Cohen and Felson (1979)

Crime will cluster in certain sectors of urban zones, while others remain crime free¹

Over 50% of crimes occur in 3% of places²

1) Sherman 1988,1989), 2) Pierce et al. 1988, Sherman et al. 1989a,b

Initial results exposed data quality issues

Process issues caused incident clustering at HQ and Local Hospitals

Not a black box - we wanted to know what was going on underneath

Graphical - Light on coding, easy to learn

Not limited to hot spots only

Easy to merge multiple sources

Ironside

POC demonstrated significant improvement over retroactive hot spots

Brought strong data science mentors who knew the technology

High-touch side-by-side model build to transfer all knowledge

End result was acquiring a department capability to do all things predictive policing, not just a hot spot scoring engine.
