Mr. Dulles. Do you have any reason to believe that those dry runs were observed by the President or known to the President, or received any publicity?

Mr. Rowley. No; they did not receive any publicity.

The Chairman. Chief, you were referring a little while ago to the revised rules.

When did the last revision take place? Has it been since the assassination?

Mr. Rowley. No.

The overall revision of the Manual of the Secret Service, was undertaken before I took office, and because it was delayed, I took it upon myself to assign a man to sit down 7 days a week, to bring this manual up to date. The overall manual has been completed. Now we have almost completed the revised advance manual.

The Chairman. And—but there has been—as yet there has been no revision since the assassination?

Mr. Rowley. No, sir; It is in the process.

The Chairman. It is in the process of being done? Very well.

Senator Cooper. I would like to ask a question. I think you stated that you took part in the procedures and methods for the protection of President Kennedy when he was—prior to his visit to Dallas.
