Mr. Hubert. It was not?
Mr. Hall. No; definitely not. This was a young kid.
Mr. Hubert. Did you see anybody else pass by going into the building to your left?
Mr. Hall. No.
Mr. Hubert. You are quite certain that no one did?
Mr. Hall. Yes.
Mr. Hubert. Are you willing to state that no one could have without your seeing them?
Mr. Hall. It is so very unlikely.
Mr. Hubert. I take it from the interval of hesitation that although your answer has been it is very unlikely, you are not willing to make the positive statement that nobody did?
Mr. Hall. No; due to one thing. There was approximately 20 minutes of tension. There was quite a bit of activity in the area. I feel very sure that only the people designated passed my long vantage point.
