Mr. Sorrels. On our investigations; yes, sir.

Mr. Hubert. And is that a custom, or is it actually a published regulation?

Mr. Sorrels. Well, we know that we are going to get in serious trouble in court if we don’t do it, because that is always—the question is always asked, especially by a defense attorney, and so forth.

And we know that we are supposed to do it.

I try to adhere to it as much as I possibly can.

Mr. Hubert. What I am trying to determine is whether that is your only personal——

Mr. Sorrels. Oh, no.

Mr. Hubert. Way of doing things, or if it is an established policy of the Service, and if so, how is it established?

Mr. Sorrels. I think it is possibly a bit of both, because it is always my practice to tell these people that we cannot promise them anything—I am talking about the people we handle for prosecution in our investigations. And that, of course, they don’t have to tell us anything if they don’t want to. We make that known—because if we do not we know if there is a trial in a case, that that question is going to be asked, and we know that under our laws that a person is supposed to be warned of his constitutional rights before he is questioned.

Mr. Hubert. Is that your version of what the law is?
