Mr. Specter. And did your distance on this occasion conform to your customary practice of being that distance behind?

Mr. Youngblood. Yes, sir.

Mr. Specter. And what is the reason, if any, for staying that distance behind the President's followup car?

Mr. Youngblood. Well, mainly so the crowd can see the Vice President, and he can see them. If you are too close behind the Presidential group, the crowd will be watching the President and will watch him as he goes by, and then they will miss the next man. So it gives the people a chance to recover and look back and see him, and they to see each other.

Mr. Specter. I show you a photograph which has been marked as Commission Exhibit No. 354, and ask you if you are able to identify what that is a picture of.

Mr. Youngblood. Yes, sir.

Mr. Specter. And what does that depict?

Mr. Youngblood. Well, it is a picture showing the main street, Houston Street and Elm Street, and the assassination occurred on Elm Street.

Mr. Specter. Are you familiar at this time with the identities of Main, Houston, and Elm?

Mr. Youngblood. Yes, sir; when I have a map such as this ahead of me.
