Mr. Liebeler. Did you let anybody out of the building after you got there?
Mr. Barnett. No, sir; until they were authorized.
Mr. Liebeler. Who was in a position to authorize people to come in and out?
Mr. Barnett. Well, of course, for sometime no one left except city, county, and Federal officers, and then after the people in the building were took into the small room there and questioned, they were brought to the door by a lieutenant, which I don't remember his name, but that was sometime after, and he brought them to the door and told us to let them out.
Mr. Liebeler. Now, it was possible that people could have left the building between the time the last shot was fired and the time you and Officer Smith stationed yourselves there?
Mr. Barnett. When I went to the door to get the name of the building, there were people going in and out then.
Mr. Liebeler. There were?
Mr. Barnett. Yes, sir.
Mr. Liebeler. Do you think it was as quickly as 2½ minutes from the time the last shot was fired until the time you got to the front door? Do you think it was that quick?
Mr. Barnett. I believe it was 2½ minutes probably from the time I ran from the back to the front. That was probably 2½ minutes. Then it took me 20 or 30 more seconds before I got to the front there.
