August 1, 2016: The Wall Street Journal reported that a federal appeals court in New York ruled law enforcement was permitted to use the “exigent circumstances” exception to the warrant requirement to obtain the GPS locations of a suspected killer. The court ruled police were legally permitted to ping the suspect’s cellphone when he was identified as possibly being involved in a murder. Law enforcement declined to obtain a warrant in fear of the safety of the undercover officers and informants who were investigating the suspect.
