Probable cause may be established through animals. Which type of evidence is described as signals for detection?

• A. Witness/informant/dispatch
• B. Signals for detection of explosives/narcotics
• C. DNA/video footage/gun casings/audio recording
• D. The length/depth/and type of their experience or training

Answer: (B)

Trained detection animals contribute to probable cause through their alert signals. When a dog or other unit detects target odors like explosives or narcotics, it produces specific cues or alerts that the handler interprets as a positive indication. These signals are the evidence in question—they’re the observable responses the animal makes that suggest the presence of contraband. This is the best fit because the item is asking for the type of evidence described as signals for detection. Other options describe human tips, general physical evidence, or the trainer’s experience, none of which are the direct alert signals produced by a detection animal.
