Explanation
Radar was introduced to traffic law enforcement in 1948. This technology allowed law enforcement officials to measure the speed of vehicles accurately and efficiently. Before radar, officers had to rely on less precise methods, such as pacing or using stopwatches, to determine a vehicle's speed. The introduction of radar greatly improved the ability to enforce speed limits and promote road safety.

Explanation
The police in Japan used 3-D Imaging technology for facial recognition to fight crimes committed by people of foreign origin. This technology allows for more accurate and detailed identification of individuals by creating a three-dimensional map of their facial features. By utilizing 3-D Imaging, the police can better match suspects to their database of biometric identifiers, increasing the effectiveness of their crime-fighting efforts.

Explanation
Brain fingerprinting is a technique that measures brainwave responses to specific stimuli to determine if a person has specific knowledge or recognition of certain information. It has been used in some cases to obtain guilty pleas from criminals by providing scientific evidence of their involvement in a crime. By analyzing brainwave patterns, brain fingerprinting can detect if a person has knowledge of details that only the perpetrator would know. This evidence can be presented in court, leading to a guilty plea from the criminal. Therefore, the statement that brain fingerprinting has been used to obtain guilty pleas from criminals is true.

Explanation
Chemical sprays were used by the police before the introduction of Tasers as a non-lethal weapon. These sprays, also known as pepper sprays or mace, contain irritants that cause temporary blindness, difficulty breathing, and intense pain, incapacitating the target. They were preferred over lethal weapons like bows and arrows or crossbows due to their effectiveness in subduing suspects without causing serious harm or fatalities. Chemical sprays provided law enforcement officers with a safer alternative to traditional weapons, allowing them to maintain control and ensure public safety.
