Mr. Stern. When you went down Main Street you found that you could not get on to the entrance to the Stemmons Freeway?
Mr. Lawson. Going the direction on the freeway towards the Trade Mart, that is correct.
Mr. Stern. Which is the direction the motorcade was to go?
Mr. Lawson. Was to go; yes, sir.
Mr. Stern. Have you ever had occasion to provide for building checks along a motorcade route when you were doing an advance, or is it just never done? This is as of the time of Dallas.
Mr. Lawson. I have never had an advance where I had buildings checked on our route.
Mr. Stern. It is not a question——
Mr. Lawson. On a moving route.
Mr. Stern. It is not a question of your instructions? You could if you wanted to, I take it? It is just a matter of your discretion and your training, is that correct?
Mr. Lawson. I don't believe it is discretion. It is just that to my knowledge only inaugurations or when a foreign president or king comes to Washington, like that where it is a motorcade route known practically for years in advance of how you are going to go do we check, start out with enough men, enough time ahead of time to check the whole route up to that time.
