What did Canadian Dr Kim Rossmo contribute to the field of geographic profiling?
Today Rossmo directs the Center for Geospatial Intelligence and Investigation at Texas State University in Austin.

What is the formula for crime?
A crime rate is calculated by dividing the number of reported crimes by the total population; the result is multiplied by 100,000.
