Mason v. United States, 244 U.S. 362 (1917)
Mason v. United States
Submitted April 11, 1917
Decided June 4, 1917
244 U.S. 362
The Fifth Amendment does not relieve a witness from answering merely on his own declaration or judgment that an answer might incriminate him; whether he must answer is determinable by the trial court in the exercise of its sound discretion, and unless there is reasonable ground, as distinct from a remote or speculative possibility, to apprehend that a direct answer may prove dangerous to the witness, his answer should be compelled.
In the absence of manifest error, the ruling of a trial judge upon a witness' objection that an answer may incriminate him will not be reversed by this Court.
The case is stated in the opinion. chanroblesvirtualawlibrary
