Mr. Hubert. Will you tell us about that—how that door operates?
Mr. Pierce. It is a door—double door.
Mr. Hubert. A double door?
Mr. Pierce. Comes together and has a lock on it, which when locked is locked both from the inside—you can’t get out, and the outside you can’t get in.
Mr. Hubert. So, when locked you need a key to go either way, is that correct?
Mr. Pierce. That’s right.
Mr. Hubert. All right, now, suppose someone had a key and went out that door, and simply let the door slam behind him, well, would that door be, at that time, locked or unlocked?
Mr. Pierce. It will be unlocked.
Mr. Hubert. To lock it you must use a key to turn the lock?
Mr. Pierce. You have to step outside the door and turn around and use your keys to lock it back.
