Mr. Shaneyfelt. That is very apparent on Exhibit 748 also, where you get the duplication of the lighting. This nob tends to reflect more light.

Mr. McCloy. It is obvious that it is right up there as a conspicuous highlight. I didn't realize that it was so indicative of the curve of the stock of the rifle.

Thank you very much indeed for your cooperation and very enlightening and very interesting testimony.

Mr. Shaneyfelt. Thank you.

TESTIMONY OF ROBERT INMAN BOUCK

Mr. McCloy. Mr. Bouck, you know the purpose for which you are here?

Mr. Bouck. Yes, I do.

Mr. McCloy. And we are very happy to have you help us to acquit ourselves of our responsibility here in determining all of the relevant circumstances in connection with the assassination of the President.

I believe you are going to give us something of the routine by which Presidents are protected?
