well I just found if anything all the authorities had to do is claim the Emergency Aid Exception to the Fourth Amendment's Warrant Requirement as their defense and justification.<quoted text>

The Emergency Aid Exception to the Fourth Amendment's Warrant Requirement
The article focuses on the legal authority of police to be exempted on the warrant requirement under the U.S. Constitution's Fourth Amendment during emergency situations. It says that exigent circumstances exception is an exception recognized by both state and federal courts in order for a police to act without warrants. It adds that the court case, Brigham City v. Stuart, showed the need for an objectively reasonable basis before a police will be legally subjected to emergency aid exception.
