Arraignment true or false - The magistrate judge determines if there was a crime committed and if there is probable cause (a reasonable ground for supposing that a charge is well-founded) that the suspect was involved with the crime.

False. In an arraignment, the accused individual is informed of the charges against them and typically enters a plea of guilty or not guilty. The magistrate judge does not determine whether a crime was committed or if there is probable cause during the arraignment process.
