Before making his way up to the patrol car, Callaway first watched Oswald make his trek all the way down Patton to Jefferson. A couple minutes had passed before Callaway actually reached the scene and he did not immediately get on the radio to report the shooting.
You really need to read his testimony more closely, Bill.
Callaway didn't wait on the porche of his office to watch the killer "trek all the way down Patton to Jefferson". He ran towards 10th street and was about halfway down Patton when he encountered the killer. If he had waited for only a minute he would have missed the killer completely.
In his testimony and his first day affidavit Callaway said he heard the shots and
ran from the porche of his office to Patton. He was on the sidewalk of Patton, near the alley that's halfway between Jefferson and 10th Street, when he saw the man running towards him with the revolver.
Tippit's killer left the scene directly after the shots. The distance he needed to cover before getting to Callaway, was from the car to the corner of 10th/Patton, which - walking at normal speed - would have taken him 20 seconds. You know this because somebody timed it in a video you were in that is on YouTube. Then he had to walk halfway down Patton (about 200 feet) to where Callaway was. That would have taken him another 20 seconds, maybe 30. You know this, you've been there yourself, you've seen just how short a distance it is. But here's a reminder;

After his encounter with the killer, which took no more that a couple of seconds, Callaway, according to his testimony, ran towards 10th street. If you add on some seconds here and there, you get to around 90 seconds to 2 minutes maximum that it took Callaway to get to 10th street and on the radio after the shots.

I don't know what you mean by "a couple of minutes" but anything more than 2 minutes, you are going to have to explain to me.
I'm being lazy today. Can you post this please?
Actually, no I can't post this because I don't know how. But I'm sure somebody else can post the document. I've seen it being posted before.
Edit: I found a copy on line for you.
