Mr. Greer. Well, it is a type of plastic. I just don't know who manufactures it. But it is clear plastic.
Mr. Specter. Is it bulletproof or bullet resistant?
Mr. Greer. No, sir. It is weather—the idea back of it was for inclement weather, that the President could be seen if the weather was too bad to have him outside. That is what we had in mind originally with it.
Mr. Specter. Do you have any personal knowledge of any efforts made to obtain a bulletproof or bullet-resistant transparent top?
Mr. Greer. Now, or before that?
Mr. Specter. Well, start beforehand.
Mr. Greer. No; I never had anything to do with that at all. I never had anything to do with anything being made for that.
Mr. Specter. Do you know what efforts have been made subsequent to the assassination of President Kennedy to obtain such a bulletproof transparent top?
Mr. Greer. Only just hearing conversation; nothing definite; no, sir.
Mr. Specter. Approximately what time, to the best of your recollection, did President Kennedy arrive in Dallas on November 22?
