That's not a "view of testimony." It's what happened.
I feel badly for Ramos, I really do. But it was his choice to throw his career away. Compean is just a disgrace to the badge.
It most certainly is not in the testimony. You made that up. Ramos never saw Compean pick up anything. Neither did Yrigoyen nor Mendez who were on the levee and saw Davila as he walked in Mexico.
After the smuggler escaped into Mexico, R & C, were walking back up to the rest of the group and Ramos specifically heard them discussing the "gunshots" with the supervisor. Ramos assumed that the supervisor had been informed that the guns had been discharged. That may not have been the correct assumption, but under the circumstances, I can see how that assumption could have been made.
My take is that the supervisor was made aware that the guns being fired by at least one other agent at the scene. But since the smuggler escaped back into Mexico, he figured that they wouldn't be seeing him again, so why write out all that paperwork and process it...?
Also, they should have never been charged under the 924-c law. There already actions being taken in Congress to have L.E. explicitly exempted from statute. Unfortunately, there a some overzealous prosecutors out there with axes to grind.
