Yes, exactly they are the pros at using Inductive Profiling. Which is? The process of profiling criminal behavior, crime scenes, and victims from the known behaviors and emotions suggested by other criminals, crime scenes, and/or victims. Inductive Criminal Profiling is generally the result of some kind of statistical analysis, or finds it's reasoning in cases outside of the case at hand.
As opposed to Deductive Profiling which is the careful forensic examination and behavioral reconstruction of a single offender's crime scene.
After the offender's behaviors have been reconstructed, the crime scene characteristics are analyzed, and the victim characteristics are analyzed. From those combined characteristics, a profile emerges with the characteristics of the individual who could have committed that specific offense, with that specific victim under the conditions present at that specific crime scene.
Remember, the cops had a warrant which specified they were looking for ROPES, HANDCUFFS. You have to be specific on a warrant. You can't just make up whatever hits your fancy.
In hindsight, after the arrest of the 2 members/operators of the LOCAL #510 CHILD PORN RING of SD/Poway, and the news article saying that ROPES,HANDCUFFS were found, it makes it look like they were onto these guys, and assumed DW was one of them.
THE QUESTION IS, where they right or wrong?
For those that say DW had CHILD PORN. First, not proven, Second, if your neighbor gets killed, and you have a bullet but no gun, Can we just hang you for it ?
