Probable cause
PC must be established first...(probable cause)...meaning you must have verification through personal experience or an informant that illegal activity is being conducted, and you must show that the telephone communications are being used to conduct or expedite this illegal activity....and usually a judge will sign a wiretap order for a period of 30 days, or a multiple of 30..
Probable cause is determined by a statement of the facts in a case, including how much evidence the police have to prove their case. Probable cause is the determination that it is likelier than not a person has committed a crime or is committing a crime. There are different levels of probable cause, including for search warrant and for an arrest warrant. A probable cause for a search warrant isn't necessarily a probable cause for an arrest, and vice versa
4th amendment
Probable cause is established in legal proceedings when there is sufficient evidence to believe that a crime has been committed or that a person is involved in criminal activity. This evidence can come from witness statements, physical evidence, or other sources that support a reasonable belief that a crime has occurred.
Most juridictions allow arrest for a felony without a warrant as long as probable cause for the arrest can be articulated.
Law enforcement officials can establish probable cause during an investigation by gathering evidence that leads them to believe a crime has been or is being committed. This evidence can include witness statements, physical evidence, surveillance footage, and other information that supports the belief that a crime has occurred.
To determine the validity of a search warrant, certain criteria must be met, including probable cause, specificity in describing the place to be searched and items to be seized, and authorization by a neutral magistrate or judge.
