Final answer:
No, a witness cannot be taken before a magistrate when trying to get a search warrant.
Step-by-step explanation:
When trying to get a search warrant, you cannot take a witness before a magistrate. The process of obtaining a search warrant typically involves the police presenting evidence and arguments to a magistrate or judge to convince them that there is probable cause to issue the warrant. Witnesses are generally not involved in this process unless they are directly relevant to the evidence or probable cause being presented.
