The differences are radical.
The two border guards who fired at Aldrete-Davila claim he had a gun. The border guard who didn't fire claims that he did not.
Compean paints a picture of himself as heroically wrestling with Aldrete-Davila in hand-to-hand combat. Ramos and Juarez didn't see anything like that - just the wiry Aldrete-Davila easily outrunning the obese Compean.
Compean says he charged Aldrete-Davila with his shotgun. Ramos says that Compean didn;t charge, but swung his shotgun at Aldrete-Davila stock first, holding his weapon by the barrel (apparently firearm safety, telling the truth, filing reports and doing crunches are all skills alien to Compean).
The stories are all very different, and only the accounts of Juarez and Aldrete-Davila reconcile and make sense.
The illegal smuggler was shot in the side of his butt. That wound would exactly fit the profile offered to the Border Agents if the illegal smuggler had a weapon and was turned to shoot at our Border Patrol.
It would also fit if Aldrete-Davila was scrambling over hilly scrubland to get to the Rio Grande.
It's pretty clear from all of Aldrete-Davila's actions that day that his primary objective was getting out of dodge. Nothing that we know about him suggests that he had the physical courage to get into a gunbattle with four armed border agents. The last thing standing between him and his escape to Mexico was Compean. According to Compean, Aldrete-Davila decided to have a fistfight with him rather than draw a weapon, and then ran from the fistfight after throwing dirt. According to Ramos and Juarez, Aldrete-Davila ran right past the slow-moving Compean without confronting him and hightailed it for the river.
Compean's story makes no logical sense and is not corroborated by his two colleagues' testimony.
It would also fit if Aldrete-Davila was scrambling over hilly scrubland to get to the Rio Grande.

In virtually no scenario can I picture it being faster to run or scramble away sideways than running away forward.
That tells me something else was happening when the illegal smuggler presented his side profile to the Border Agents as he was fleeing from them.
It's clear you and I will not agree on this, good day to you.
