In cases involving excessive force, courts typically apply an objective reasonableness standard, as established by the U.S. Supreme Court in Graham v. Connor (1989). This standard evaluates the actions of the officer from the perspective of a reasonable officer on the scene, considering the information known to the officer at the time of the incident. Factors such as the threat posed by the individual, the availability of alternative methods, and the need for immediate action are all taken into account.
In Relf v. City of Troy, the court was tasked with applying this standard to the actions of a police dog, which is considered a tool of law enforcement. Just as with human officers, the use of a police dog’s force must be reasonable under the circumstances. This includes considerations such as the dog’s training, the handler’s supervision, and the foreseeability of harm to innocent bystanders.
