Final answer:
A person can be held in another parish on a warrant for probable cause. This includes situations of fleeing from justice, requiring probable cause for arrest, and following due process, such as presentment or indictment by a Grand Jury and the right to a writ of habeas corpus.
Step-by-step explanation:
A person can be held in another parish on a warrant for probable cause. This means that they cannot be detained without there being a reasonable basis for believing that they have committed a crime. However, exceptions do exist where police can arrest individuals suspected of felonies without a warrant as long as probable cause exists.
For misdemeanors or minor crimes, an arrest can occur if the police witness the crime themselves. The requirement for an arrest due to a crime in another jurisdiction also ties into the principle that a person charged with treason, felony, or other crime who has fled from justice can be extradited back to the state having jurisdiction of the crime upon demand of its executive authority.
In the United States, the Fifth Amendment of the Constitution provides that no person shall be held to answer for a capital or otherwise infamous crime unless on a presentment or indictment of a Grand Jury.
Additionally, the Sixth Amendment guarantees the right of an accused to be informed of the nature and cause of the accusation against them. The process of writ of habeas corpus is also fundamental in rule-of-law countries, allowing individuals who are jailed to demand to be brought to court and informed of the reasons for their detention.
The concept of bail is important as it offers an accused person the option to be freed pending trial after paying a certain sum of money. However, it is possible for bail to be denied if the individual is deemed likely to flee or poses a risk to the community.
