How is an arrest warrant related to probable cause?

An arrest warrant is fundamentally linked to the concept of probable cause, as probable cause is necessary for a court to issue a warrant. This means that before a warrant can be granted, law enforcement officials must present sufficient facts or evidence that would lead a reasonable person to believe that a crime has been committed and that the individual named in the warrant is responsible for that crime.

In essence, establishing probable cause is a critical step in the process of obtaining an arrest warrant. It ensures that there is a legitimate basis for the arrest, protecting individuals from arbitrary or unjust detainment. Courts require this legal threshold to prevent abuses of power and to uphold an individual's rights. Therefore, without probable cause, an arrest warrant cannot be lawfully issued. This highlights the importance of probable cause in balancing law enforcement duties with civil liberties.
