6. Probable cause is defined in which of the following? A. The Fourth Amendment B. The Fifth Amendment C. The Law Enforcement Handbook D. The Fourth Constitution

## Step 1<br />The question is asking where the term "probable cause" is defined. Probable cause is a legal term that refers to a reasonable belief that a person has committed a crime. It is a standard used by law enforcement to justify arrests, searches, and seizures.<br /><br />## Step 2<br />The Fourth Amendment to the United States Constitution is the correct answer. This amendment protects citizens from unreasonable searches and seizures by the government. It requires that a search warrant be judicially sanctioned and supported by probable cause.<br /><br />## Step 3<br />The Fifth Amendment, on the other hand, deals with the rights of individuals in criminal cases, including the right against self-incrimination and the right to due process.<br /><br />## Step 4<br />The Law Enforcement Handbook and the Fourth Constitution are not standard legal documents or amendments in the United States, and therefore, they do not define probable cause.
