Which concept describes the minimum information legally required before entering a subject into a criminal intelligence file under 28 CFR Part 23?

In crime series analysis, what is the key indicator that distinguishes a 'series' from random clustering?

Answer: Allow the individual to leave if there is no other basis for detention

Which analysis technique divides a geographic area into cells and measures crime density per cell to guide resource allocation?
Answer: Grid cell analysis (kernel density estimation)
Kernel density estimation and grid cell analysis quantify crime concentration across defined spatial units, enabling data-driven resource deployment decisions.
