In the case of United States v. Weaver, the appellate court was faced with the question of whether or not police officers used excessive force in making an investigatory stop of a suspect. Based on all the facts of the case, the appellate court agreed that force may be used to make an investigatory stop and that excessive force was not used in this case. The other article notes that police officers must be aware of precursor chemicals due to the hazard they pose to police on routine patrol. These dangerous chemicals can explode, burst into flame, or give off poisonous or caustic fumes. They are equal to the power of firearms in their potential to cause death or serious injury. Therefore, police should use caution when they believe they may be near these substances. Photographs and questions and answers
