The Chairman. Officer, you were in uniform that day?
Mr. McDonald. Yes, sir.
The Chairman. Did the blow he gave you on your nose leave any mark?
Mr. McDonald. Well, for 2 days I had some swelling. It didn't break the skin or anything. Some of the force was taken by my top. It hit the bill of my cap and my nose.
The Chairman. And the scratch from the corner of your eye down to the corner of your mouth came from the pistol?
Mr. McDonald. Yes, sir. As I was taking the pistol away, clearing it from his body. Yes, sir.
The Chairman. I think that is all. We are very glad you are able to be with us today.
Mr. Ball. There is one thing.
I have marked an exhibit, 520.
(The document referred to was marked Commission Exhibit No. 520 for identification and received in evidence.)
