Mr. Bouck. This is an effort to detect people who might intend to harm the President, people who make threats against the President, people who do things that indicate they may intend to harm him, and the various sort of things we do to see that they do not accomplish that, to prevent them from accomplishing them.

Mr. Dulles. Does your particular office maintain the central files for your agency?

Mr. Bouck. For this function?

Mr. Dulles. For this function.

Mr. Bouck. Yes.

Mr. Dulles. I mean if the FBI sent in to the Secret Service a name or a description of a particular man, or a particular area that would be filed in your office?

Mr. Bouck. That is right.

Mr. Dulles. Do you file that alphabetically, by location or how do you develop those files?

Mr. Bouck. The information in its file jackets is filed numerically but it is indexed alphabetically and by location as well as by certain other characteristics that may help us find it.

Mr. McCloy. To come back to this matter of bugging again, do you feel that you are thoroughly well equipped, which is a repetition perhaps of what Mr. Dulles asked, Mr. Dulles' question, do you have an expert staff that know this business and that keep up to date with the developments in the area, and that can constantly keep your equipment in shape?
