Police equipment now includes the fingerprint wand and the night scope. The fingerprint wand costs $150. It enables police personnel to lift and process fingerprints at the crime scene rather than at the laboratory. The night scope enables police to see in almost total darkness without being seen by others. These devices cost $1,000 each and increase police safety by replacing flashlights. Another piece of equipment is a remote-controlled robot with a camera; it can deal with dangerous situations involving bomb threats and barricades. A student-organized crime prevention effort at one university focuses on preventing date rape. Student patrols at another university focus on the neighborhoods around the campus.
