We didn't have a regular courtroom where you could call in a witness and, uh, examine him with a secretary present and someone else cross-examining or, uh, securing his rights. We, uh, if we were taking testimony from friendly witnesses, we'd take an affidavit from them. He'd swear to it before an officer. If it was from a hostile witness, um, we would interrogate him privately, uh, in order to, uh, see if we could ascertain the truth. And when we reached the point where we felt we had ascertained the truth, we asked him to write it out in his own hand and subscribe to it as being true, and usually brought in an officer to witness that, uh, or to, uh, take a separate deposition, uh, under more favorable circumstances from a point of view of trial. And, uh, that was the evidence that we then used.
