Final answer:
An investigator's courtroom checklist does not include a personal firearm, but does include case documentation, a witness list, and courtroom attire.
Step-by-step explanation:
The investigator's courtroom checklist does NOT include a personal firearm. Items like case documentation, a witness list, and appropriate courtroom attire are essential for courtroom proceedings. The investigator must be prepared with all necessary documentation related to the case, a list of witnesses that may be called upon to testify, and must dress in a professional manner to maintain the decorum of the court.
For reference to a related topic, under the Sixth Amendment, the right to remain silent is not protected; this right is in fact protected by the Fifth Amendment. The Sixth Amendment guarantees the right to a speedy trial, the right to trial by an impartial jury, and the right to cross-examine witnesses.
In a typical courtroom setup in the United States, as described in the reference, the jury is seated along one side of the courtroom, with the judge and witness stand positioned on one end, and the tables for the defense and prosecution facing each other across the room.
