A recent case from the New Mexico Court of Appeals addressed the validity of the consent to a search under the 4th Amendment. The case of State v. Norman Davis involved the search of an individual's property for marijuana.
In a joint operation, the New Mexico State Police, the New Mexico National Guard and officers from a number of other law enforcement agencies entered Mr. Davis' property to investigate the presence of marijuana. The numerous officers were heavily armed with handguns and AR-15 semi-automatic weapons. In addition, the operation included two Army National Guard helicopters which were hovering over the residence at the time that contact was made with Mr. Davis.
